How to adjust the length of the conveyor belt installation

The conveyor belt , the installation is particularly important. To ensure correct installation of the belt can not only avoid unnecessary defects, and also allows the belt to

work better .
      When installing the conveyor advance Telescoping conveyors for the entire conveyor belt to be installed careful planning calculations, whether new or old belt replacement belt installed ,

otherwise it is likely to cause the situation to take a long conveyor belt , is a direct consequence weight ( weight counterweight ) hit the ground

Led start to slip . Although there was no problem , no problem test , but the position of the lower configuration , running two or three months later , with heavy drooping, hit

the ground when starting . This is Telescopic belt conveyor because the installation process does not take into account the elastic deformation and plastic deformation of the belt . Conveyor

When installing or too short , you should leave a margin for future maintenance. If the length of the minimum basic tension in the spiral . Joint problems after a period of use

, the conveyor belt margin is not sufficient to redo the joints, had to re- install the new belt. This makes our conveyor belt made

Become a go to waste . While enabling enterprises subject to certain unnecessary losses. This is what we want to see the production situation . Ideal conveyor installation is

that after installing the conveyor belt of moderate length ( we should take into account summer and winter temperature differences affect the expansion of the conveyor belt )

It is best to set aside a margin joints , which can effectively prevent the installation length of inappropriate questions .

Use mobile belt conveyors

energy consumption , standard parts, etc. , belt conveyor is widely used in mining , metallurgy , coal and other departments,

Used to transport loose materials Flexible skatewheel conveyor or items , according to the transport process requirements, can be a single conveyor can also be composed of multiple components or other

transportation equipment horizontal or inclined conveyor system to meet the different needs of arrangement type Telescopic conveyor of operating line . Belt Conveyor , also known as belt conveyors,

conveyor

According to the principles of friction drive belt and exercise , for conveying bulk density of less than 1.67 / t / cubic meter, easy to dig a powder, granular, small block of

low- abrasive materials and bags of materials such as coal , gravel , sand , cement , fertilizer , food and so on. Belt conveyor can be at ambient temperature

Within the range of -20 ℃ to +40 ℃ use , sent the material temperature is less than 60 ℃. The captain and assembly in the form of belt conveyor can be determined according to

user requirements , power transmission roller can also be used with a driving device frame . Belt conveyor is stone, sand production line essential

Equipment !

Introduction roller conveyor

Mainly by the roller conveyor rollers , racks , brackets, drive part and other components , roller , roller conveyor is to rely on friction rollers rotating between the article

and goods to move forward . Their drivers can be divided into non-powered roller conveyors, powered roller conveyor in power roller conveyor

Machine , the driving roller is steel roller conveyor generally not a method using a separate current -driven approach , but using a multi- group drive motor and gear combinations used , then by a

chain drive, belt drive roller to rotate .

Structure: can be divided into flexible conveyor power by driving drum line and drum line without power , according to arrangement can be divided into horizontal conveyor drum line, drum line and

cornering inclined conveyor drum lines . Can also be specially designed according to customer requirements to meet each [ 1 ] [ 2 ] class customer requirements. Standard gauge

drum line

The width of 200,300,400,500,1200 mm and so on. Also can use other special customer needs. Turning drum line standard turning radius of 600,900,1200 mm , etc., customers can

also use other special needs . Drum diameter rollers used straight section 38 ,

50, 60,76,89 mm and so on.

Roller conveyors are the following :

1, the transmission length of the object , the width and height ;

2 , the weight of each conveyor unit ;

3 , the bottom position of the conveyance object ;

4 , any special requirements on the work environment ( for example: humidity, temperature, effects of chemicals , etc. ) ;

5 , conveyors are unpowered motor driven type or style .

To introduce you to the belt conveyor

Also called conveyor belt conveyor or belt conveyor is composed of rhythmic flow line indispensable economic conveying equipment. Ability to belt conveyor belt conveyor into

heavy , medium and light duty belt conveyor powered roller conveyor belt conveyor . Form of the structure can be divided into

Horizontal , climbing , turning, spiral and other forms of transportation . Meanwhile belt conveyor with transport capacity, transmission distance, simple structure, easy to

maintain, easy to implement procedures to control and automation for electronics , hardware , machinery, chemicals , food, forest , mining

Hill , rubber and other industries. Material belt conveyors of a wide range of structural forms . Except for the delivery of ordinary materials , but also to meet the oil, heat

, corrosion-resistant , skate roller conveyor anti-static material handling special requirements . Conveyor is in a certain line continuous conveyor

Materials handling machinery , also known as continuous conveyor. Conveyor can be horizontal, inclined and vertical conveyor can also be composed of the space of the transfer

line , the transfer line is typically fixed. Conveyor transport capacity , long distance , but also in the transportation process while completing a number of process

operations, so

Is widely used. Can be a single conveyor can also composed several other transportation equipment or horizontal or inclined conveyor system to meet the different needs of

arrangement of the operating line . Transportation machinery by works can be divided into: belt conveyors, screw conveyors , bucket elevators

How to maintain the relationship between the roller and the conveyor

Roller conveyor is an important component , the type , quantity , quality idlers direct impact on the quality of the conveyor . Roller conveyor forward rotation resistance and

resistance to the belt conveyor is mainly attributable to the resistance of 50% to 85%. The captain of the belt conveyor heavy duty conveyor over 80m total resistance is calculated , the total

Resistance to attacks such as the length of the conveyor in accordance with the selected charge coefficient , friction coefficient and installation simulation and working

conditions related to the length of the conveyor , carrying the rotating part of the mass per unit length of the branch roller rotating part of the quality return idler unit

Criteria for the selection of food conveyor belt speed of

    ( 1 ) delivery of large , shipped with a wide , should be selected with a higher speed .

    ( 2 ) long horizontal conveyor , should be selected with a higher speed ; conveyor inclination larger, shorter delivery intervals , the belt speed should be lower .

    ( 3 ) the material is easy to roll , large size , Flat belt conveyor strong abrasive , or simply dust as well as higher demand for sanitation , should use the lower belt speed .

Belt speed and the angle of the line Elevator conveyor bandwidth to transport , material properties , fragmentation and related conveyor when the conveyor transporting up big dip belt speed

should be low ; when the next operation, the belt speed should lower ; horizontal transport , the high belt speed can be selected . taking into account the level of

transportation, short length , the demand for belt speed

Is 2m / s.

Check the location of the material on the conveyor belt

A conveyor belt of deviation and its treatment

Deviation conveyor belt conveyor running is one of the most common faults . There are many reasons for deviation , the main reason is to install low precision and routine

maintenance is poor.

During installation , between the head rubber belt conveyor and tail rollers , the intermediate roller on the same center line as possible , parallel to each other and to ensure that the belt is not

biased or less biased. In addition, the strap connector to the right, should be the same on both sides of the perimeter .

During use , if there is deviation , they have to make the following checks to determine the cause , be adjusted. Incline Belt conveyor Conveyor deviation always check the location and processing

methods are:

1, check the rollers do not coincide with the center line of the transverse conveyor longitudinal centerline . If the values ​​do not coincide more than 3mm, you should take

advantage of the elongated mounting holes on both sides of idlers be adjusted . The specific method is biased on which side of the conveyor belt , which the lateral conveyor

idlers forward

Forward direction or another after the side shift.

2, check the head , tail rack-mounted bearing deviation of two planes values. If the deviation is greater than two planes 1mm, the adjusted response to the two planes in the

same plane. Adjustment of the head drum is : If the conveyor roller deviation to the right , then the right side of the roller bearing should move forward

After moving or left bearing shift ; If the conveyor roller deviation to the left , the left side of the roller bearing should move forward or to the right bearing after shift.

Rear roller adjustment method and the head drum opposite.

3, check the position of the material on the conveyor belt . Material is not centered on the conveyor cross-section , will lead to the conveyor belt deviation. If the material

is biased to the right, then the belt deviation to the left , and vice versa. In should be used as much as possible so that the material in the middle. To reduce or avoid such

conveyor run

Partial increase the blocking plate , change direction and position of the material.

When food is pulled off the conveyor belt conveyor

Tilt grain conveyor , when the belt is pulled off due to an accident , the belt material , and to produce it at the decline clogging . To prevent pulling up the rear of the

conveyor decline required to set traps for broken belt protection. Role trap is broken belt , the automatic action to seize the conveyor belt

The conveyor belt to stop. It therefore requires portable conveyor quick response, there is as small as possible braking time and braking distance. In normal operation the belt conveyor belt is

not worn , no additional resistance , Plastic belt conveyor without reducing the productivity of the conveyor . Material filled extent and reliability of its work without the belt

Conveyor installation angle impact . Trap can be used , such as a wedge and wheel stop mode .

1 ) It is a wedge-shaped trap consists of two rollers mounted on brackets , guide ramps , locking mechanism and glide board composed . When pulled off the conveyor belt ,

detected by the speed sensor , and to disengage the locking device , slide the bracket down the conveyor belt was caught between the wedge and skateboards

. Completion of the conveyor belt arresting work .

2 ) It consists of upper and lower rollers catcher wheel brake , limit switches , spring preload and compression pulley components. The upper and lower sides of the belt brake

wheel grip , which can be rotated about its axis relative to the conveyor belt for rotation without sliding . When broken belt , the conveyor and material gravity is run by

upward

Into sliding down due to the brake drum rotates in only one direction can not be rotated in reverse direction , the brake wheel and the belt slip , slide under the action of

friction , to rotate with the wheel brake lever , two wheel brake soon the conveyor belt grip , played the role of conveyor arrest . In braking delivery

With the same limit switch signals .

Food matching bandwidth conveyor

Food conveyor belt speed transmission capacity and bandwidth proportional , with conveyor belt width, thickness increased, the deviation has been reduced, with a high -speed

desirable values ​​.

 Increase the belt speed , belt conveyor can transport belt conveyor design in the same capacity with a smaller bandwidth conditions , while reducing the load conveyor line , the tension decreases,

the strength of belt conveyor manufacturer lower prices cheaper conveyor can be used. Belt speed is increased, the size and mass of the drive means are correspondingly reduced . Therefore

Improve with speed , reduce the bandwidth of great economic significance. However, with the increase in speed may be raised dust transport , causing material damage to be

shipped , but also in the loading section , cleaning section , etc. to increase belt wear.

Brown rice, etc. ) available portable conveyor optical sorting machine . Each slot machine in the parallel installation of photoelectric sensors, food was fine stream flows through the thin,

narrow slots . When the colored particles flowing through the light zone , its reflective properties procure sensor sends information, and then open the shutter slot at the

bottom of the colored particles discharged

Tablets. This equipment is good, but the production rate. Of rice or brown rice has Mans barnyard barnyard grass can be electrostatic machine, food was uniformly thin layer into

the machine , there are tares due to the polarization properties of mango in a strong electrostatic field significantly biased side of the machine to be ranked outside the

machine .

Separated by flow characteristics using food particles and impurities suspended in the airflow velocity size separation . Fan belt hand cars and winnowing machines are winnowing

the application of this principle when artificial . Winnowing machine cycle can be used to clear the food shown in the light impurities . Food and feed through the hopper

Air flow evenly into the roll , drop to the bottom by a screw conveyor discharge machine , the impurities were carried by the suction duct airflow into the dust chamber ,

settling in the end portion of the rear by another screw conveyor from the plane , the air back into the blower continue recycling

Selection of Grain conveyor power devices

    1 heat problem

    Cooling grain conveyor power devices probably accounted for the entire amount of heat inverter in general, it has a Belt conveyor direct impact on the life of the drive , thereby

affecting the life of the conveyor length .

    2 . Electromagnetic Compatibility

    The main drive control circuit and the main circuit composed of two parts , the main non-linear switching circuit , the inverter itself so that the harmonic interference.

The control circuit of belt conveyor design the inverter is a weak signal , small energy circuit , so the drive can not be vulnerable to interference caused workers

Made . Therefore , to solve the interference problem of electromagnetic compatibility is a key technology explosion proof inverter working properly .

    3 Selection issues of power devices

    1140v is unique to China's coal industry, a voltage level , while not currently on the market for constant torque load start and speed control 400kw/1140v mine explosion-

proof inverter products. Therefore, the selection of the power device drive is also an important research work

.

    4 . Proof housing design

    Explosion-proof enclosure is designed to take into account the heat , explosion-proof structure, and electromagnetic compatibility and other technical requirements.

Selection of food conveyor lubricants and additives

1 . Ensure the quality of assembly . Can be purchased or homemade when some special tools, gear parts removal and installation , try to avoid tapping with a hammer and other

tools ; replace the gear , when worm , heat exchange manufacturers try to use original parts and replace in pairs ; assembly output shaft , pay attention tolerances

; Difficult to use when dismantling anti-adhesive or red lead oil to protect the hollow shaft , with the area to prevent rust or wear debris, repair.
2 . Lubricants and optional additives . Worm air to water heat exchanger gear reducer 220 # gear oil is generally used for heavy-duty , start frequently, poor environment reducer, can use some lubricant

additives, so that when you stop running gear gear oil is still attached to the gear surface, forming Paul

Protective film to prevent direct contact between the metal heavy load , low speed , high torque and starts. Additives containing modifiers and anti- leak seal agent , so seals

remain soft and flexible, reduce oil leakage.
3 . Select reducer installed. Lower position allows, try not to use vertical installation . When installed vertically , install a lot more than the level of the amount of oil

added , could easily lead to fever reducer and oil spills.
4 . Establish lubrication maintenance system. According lubrication "five " principles of gear maintenance , so that each person has a responsibility gear regularly checked and

found significant temperature exceeds 40 ℃ or oil temperature exceeds 80 ℃, the quality of the oil or oil drops copper is found in more

When and generate abnormal noise and other phenomena, to immediately stop the use , timely maintenance , troubleshooting , replacement of oil . When refueling , pay attention to

the amount of oil , to ensure correct gear lubrication .

Requirements shaftless screw conveyor

1 shaftless screw conveyor when no load should start , that no starting material in the cabinet after the start before automated sorting machine being fed to the conveyor .
2 When the initial feed conveyor , should be gradually increased. Feeding capacity until delivery of the rated capacity , feeding should be uniform, or likely to cause transport

of materials product plugs, hot water heat exchanger drive overload , so that the entire conveyor damage.
3 In order to ensure that no-load starting conveyor requirements , before stopping the conveyor should stop feeding, conveying the material in the cabinet to stop completely

before transporting finished running.
4 materials shall be transported in the bulk material mixing hard to avoid the death spiral card damage conveyor
5 regular testing work in the use of various parts of the state conveyors , attention is loose fasteners , if found loose parts . Should immediately tighten the screws , so that

re strong.
6 conveyor cover should not be removed while the machine is running, in order to avoid accidents.

General conveyor design

1 , parts of all equipment will be in strict accordance with national standards for the design , processing and production , to meet users ' various tender technical

requirements and process requirements , and comply with the laws on production safety , environmental protection, check weighers fire protection and other aspects of the country , regulations

and industry standards.

3 , the main components of all equipment such as rollers , drives, rack , roller and so completely by the quality assurance system in the test specifications for testing and

production, guarantee to provide users with the most satisfactory products.
4, the unit of measurement using Chinese legal units of measurement .

Screw Use and Selection Considerations

Caution:
Screw not transport perishable , viscous , easy caking materials because these materials at the time of delivery food metal detector will be bonded to the helix , and subsequently rotated without

moving the plot forward Pharmaceutical metal detector or materials formed in the hanging bearing plug, but it does not work .
Selection Notes :
Given the range of applications and features screw conveyor , the user at the time of selection, should be considered according to the environment and transportation of

materials , the balanced, reasonable selected in order to avoid unnecessary trouble and loss.

Belt conveyors can be economical and effective delivery of various materials

Components:
Mainly from the rack , pallet conveyor conveyor belts, roller belts , a tension means transmission device and other components. The body is made of high quality steel connections from the front

Order of the conveyor belt . There gear motor drive and electric drum -driven in two ways.
Advantages :
In industrial production , belt conveyor can be used as production constitutes a link between the continuous production of machinery and equipment in order to achieve continuity

and automation of production processes , improve productivity and reduce labor intensity , with a transport capacity, simple structure, easy maintenance , excellent standardized

components

Point .

Failures and approach conveyor belt

Conveyor belt Common Cause analysis and treatment of the conveyor belt can be used as the transport machinery has been widely used in coal , grain, flour mills and other

industries. Can transport bulk material ,belt conveyor design  the material can be transported in bags . Users when installing and using such equipment, often out

Now some of the belt conveyor manufacturer cause of the malfunction is not clear , not much processing methods. In this paper describes the causes and treatment of common faults such equipment . A

conveyor belt conveyor belt slippage and solutions in operation , slipping for many reasons , common causes and solutions are:

1, the initial tension is too small. Leave the tension roller conveyor at the inadequacy of the conveyor belt slippage. This situation generally occurs at startup , the solution

is to adjust the tensioning device , increasing initial tension . 2 , the friction between the drive roller and the conveyor belt is not enough cause skidding. Its not original

Mostly due to water or humid environment on a conveyor belt. The solution is to add some rosin on the end of the drum . But be careful not to hand dosing , and the application

of the blast blowing equipment to avoid personal injury . 3 , the rear roller bearing is damaged or does not turn up and down roller bearing damage does not turn too much.

Cause of the damage is too much tail drifting without timely maintenance and replacement of damaged parts or rotation is not flexible , so that increased resistance caused by

skidding. 4 , starting too fast can also form slip. At this point may slow start . Such as the use squirrel cage motor, then start jogging twice

, The slip phenomenon can be effectively overcome . 5 , the belt load is too large, more than the motor capacity will slip. The upside is that this time slipping motor plays a

protective role. Otherwise, a long time the motor will be burned. But for running it is slipping accidents. Overcome conveyor

Slipping , slipping the first to find the reason , before taking effective remedial measures . Second, the deviation and its handling conveyor belt conveyor belt running

operation is one of the most common faults . There are many reasons for deviation , the main reason is to install low precision and routine maintenance

Poor maintenance . During installation , between the head and tail rollers , the intermediate roller on the same center line as possible , parallel to each other and to ensure

that the belt is not biased or less biased. In addition, the strap connector to the right, should be the same on both sides of the perimeter . During use , if there is deviation

, they have to make in order to

Check to determine the reason for adjustment . Conveyor deviation always check the location and processing methods are: 1, check the lateral misalignment roller conveyor belt

centerline longitudinal centerline . If the values ??do not coincide more than 3mm, you should use both sides of the elongated idlers Ann

Mounting hole to be adjusted . The specific method is biased on which side of the conveyor belt , which the lateral direction of the conveyor belt idlers advancing forward, or

the other side of the shift. 2, check the head , tail rack-mounted bearing deviation of two planes values. If the deviation is greater than two planes 1mm, then respond

Adjusting the two planes in the same plane . Adjustment of the head drum is : If the conveyor roller deviation to the right , then the right side of the roller bearing should

move forward or left bearing setback ; If the conveyor roller deviation to the left , then the left side of the roller bearing should move forward

Or after the shift to the right bearing . Rear roller adjustment method and the head drum opposite. 3, check the position of the material on the conveyor belt . Material is not

centered on the conveyor cross-section , will lead to the conveyor belt deviation. If the material is biased to the right, then the belt deviation to the left , and vice versa

Ran . In should be used as much as possible so that the material in the middle. To reduce or avoid such blocking plate conveyor deviation increase , change direction and

position of the material.

Stainless steel mesh belt conveyor

A stainless steel mesh belt conveyor line metal mesh belt conveyor , using wire mesh belt prepared for the carrier , in the middle on both sides wear pin connection with the

installation of the chain , heat exchange manufacturers allowing the use of a chain sprocket chain conveyor belt along the direction Sports ; also directly with a special plastic bag roller to

Direct drive with Network for the former are generally applicable to materials heavier and longer length delivery form , used for cooling , drying and other requirements of the

transportation industry , air to water heat exchanger and therefore the density of the network with a more dilute , which generally use a relatively dense mesh belt for smaller transport materials or

special short distance

Special transport object , such as a belt conveyor of a ferromagnetic material . Heavy mesh belt conveyor is generally no longer than 15 meters, a width of not more than two

meters ; lightweight stainless steel mesh conveyor belt length is generally not more than 10 meters .
We can use Teflon mesh conveyor belt at the time of delivery of the high temperature and density of the mesh belt also ( 2 * 2, 4 * 4 ) optional temperature from -10 degrees

Celsius to 200 degrees Celsius , as Teflon mesh belt softness and therefore will not damage the material of choice for a special delivery of the ambient temperature

The new principle of pneumatic diaphragm pumps and transport machinery for occasions

Membrane pump is a new type of transportation machinery , is currently one of the most innovative pumps . Using compressed air as a power source for a variety of corrosive

liquid with particles , high viscosity , belt conveyor design volatile, flammable, poisonous liquid can be pumped exhaust . Its pneumatic diaphragm

There are four kinds of material: plastic , aluminum , cast iron, stainless steel. Diaphragm pumps were used NBR, neoprene , Viton , PTFE , depending on the liquid medium , poly

vinyl forty-six . To meet the needs of different users . Placed in a variety of special occasions , normally used for pumping species

Suction pump can not belt conveyor manufacturer regulate the media , have achieved satisfactory results.
A pneumatic diaphragm pump for occasions
Because of pneumatic diaphragm pumps with the above characteristics , so diaphragm in the world since the birth of the pump is gradually into other markets , and some of them

occupied . Such as: painting, ceramics in the diaphragm has an absolute dominance , while in some other industries, such as

Environmental Plastic belt conveyor protection, water treatment, construction , sewage, Fine Chemicals is expanding its market share , and has other pumps irreplaceable . Pneumatic diaphragm

advantages:
1, due to air powered , so flow with backpressure ( outlet resistance ) to automatically adjust to changes , suitable for high viscosity fluids . The centrifugal pump operating

point is water as a benchmark to set a good , if slightly higher viscosity of the fluid, you need to complete reducer or frequency modulation

Speed ​​control , the cost will be greatly improved , the gear pump is the same .
2 , an explosive environment using reliable and low cost pneumatic pumps , such as fuel , gunpowder, explosives transport because: first , it is impossible to produce a spark

after grounding ; Second , the work is no heat generated , the machine does not will overheat ; third , the fluid does not overheat because the diaphragm

Fluid agitation minimum .
3 , at the site of bad places, such as wastewater construction sites, mines , because the sewage impurities and are complicated, easy to plug the pipeline , so that the pump on

form load is too high , the motor heat vulnerability . Pneumatic diaphragm pump can flow through the particle and adjustable tube

Automatically stop when the road to clear blockage .
4 , another small diaphragm easy to move , no foundation , representing the ground is extremely small, easy to install and economical. Materials can be used as portable pump .
5 , there is hazardous , corrosive material handling , the diaphragm material can be completely separated from the outside world .
6 , or the number of tests to ensure that no foreign material contamination .
7, can be used to transport fluids relatively unstable chemical nature , such as : a photosensitive material , such as flocculation liquid . This is because the low- shear

diaphragm little physical impact on the material.
Second, the working principle of pneumatic diaphragm pumps
1 , compressed air powered .
2 , is a deformation caused by the reciprocating diaphragm pump volume change of volume , it works similar to the piston , due to the characteristics of diaphragm pump works ,

so diaphragm pump has the following characteristics : ( 1 ) the pump does not overheat : Compression air as the driving force in the expansion of the exhaust is an endothermic

Process , when the pneumatic pump operating temperature is lowered , no harmful gas emissions. ( 2 ) does not have a spark : pneumatic diaphragm pump without electricity for

power, ground and then prevent static sparks ( 3 ) through a liquid containing particles : Because the volume of imports and ball type work , it is not easy

Blocked . ( 4 ) low shear force on the material : how work is sucked into how vomit , so a minimum of agitation materials for the delivery of unstable substances ( 5 ) flow can

be adjusted , can be installed at the outlet section of the material valve to regulate the flow . ( 6 ) having a self-absorption function. ( 7)

In the dry run , without danger . ( 8 ) can dive work . ( 9 ) can be transported very fluid range from low viscosity to high viscosity , obtained from the viscous resistance . (

10 ) There are no complicated control system, no cables, fuses, etc. . ( 11 ) small size, light weight , they

Mobile . ( 12 ) without lubrication so maintenance is simple and does not pollute the working environment due drip . ( 13 ) pump will always be able to maintain efficient , not

because of wear and tear is reduced. ( 14 ) 100% of energy use , when to close the outlet , the pump automatically shut down, moving equipment , wear and tear, overload, fever

( 15 ) There is no dynamic seal , easy maintenance to avoid leaks. Work no dead spots .

Transportation machinery for use by end-use can be divided into sub

Conveyor technology advantages

The first is its reliable operation. In many important production units require continuous operation , such as the transport of coal power plants conveying bulk materials steel

mills and cement plants , as well as loading and unloading of ships in the harbor , are using belt conveyors . On these occasions , such as shutdown , the loss is huge

. When necessary, the belt Flexible skatewheel conveyor conveyor can take a class to a group of continuous work .
Conveyor low power consumption . Due to the material and almost no relative movement of the conveyor belt , not only the running resistance is small ( about 1/3-1/5 scraper

conveyor ) , but also gravity skatewheel conveyor for cargo wear and crushing are small , high productivity . These are conducive to lower production costs.
Transport conveyor line adaptable and flexible. Line length according to the need. Short as a few meters , length up to 10km or more. Can be installed in a small tunnel above

the ground can also be set up in the traffic chaos and danger areas.
According to process requirements , can be very flexible conveyor from the feed point or points that can also be to multiple discharge points or several sections . When both the

feed at several points on the conveyor ( conveyor under Coal bunker ) , or the longitudinal direction along any point on the conveyor

Through the uniform feeding equipment to feed conveyor , belt conveyor has become a major transport trunk .
You can stockpile conveyor roadway below reclaimer at coal storage field , when needed , but also the various different materials mixed heap . Material may be simply discharged

from the head of the conveyor , can also be moved or plow unloader unloading vehicle longitudinal direction at any point of the discharge conveyor .

Belt Conveyor Safety Tips

1 . Fixed belt conveyors should be installed on a solid basis ; mobile belt conveyor in operation before the wheels should be symmetrical wedge . Parallel multi-machine

operation, should stay out of each other more than 1m channel. There should be no prejudice around the conveyor working deposits.
2 . Before starting , you should steel roller conveyor adjust the belt tension , the buckle should be firm, bearings, gears, chains and other transmission parts should be good , roller and protective

devices should be complete, then zero or electrical protection should be well grounded , conveyor belt and the roller width should consistent .
3 . When you start , you should load operation , to be operating normally , even before loading . May not start after the first charge .
4 . Number of tandem feeding conveyor , the discharge end of the start sequence should start until all operating normally , before loading .
5 . When feeding, should flexible conveyor be aligned with the center and should reduce the height of the conveyor belt , reducing blanking on the conveyor belt, roller impact. Feeding should be

kept uniform.
6 . Operation, should always observe the mechanical functioning , when found conveyor belt slack or deviate phenomenon, should be adjusted down .
7 . Job, forbids any person from the conveyor belt passing below , or from above cross. Belt slip, prohibited by hand pulling . Prohibited operation to clean up or repair

operations.
8 . When conveying bulk materials , conveyor belts should be installed on both sides of the fence and other protective plate or device .
9 . Conveyor discharge height adjustment should be carried out in the parking . After the adjustment, tighten the coupling nut should and should plug in insurance sales .
10. Transportation needs to stop, you should stop loading, unloading the material on the conveyor belt to be exhausted only after the shutdown. Several conveyors in series

operation shutdown, should start on the discharge end of the shutdown sequence .
11 . When a power outage or other causes sudden shutdown , immediately cut off the power , the material on the belt removed, upon call or troubleshooting before then power

starts running.
12 . After the work is completed , the power should be disconnected, locked the power switch box , clear the conveyor sand, covered with a rain hood motor .

Correctly grasp the installation and use of the conveyor

An accurate installation and maintenance to ensure that the specifications of the same scraper chain , rolling at flexible operation .
To ensure flatness of the inner wall of the cabinet , will not allow the interface flange and the plastic chain conveyor rail up and down the wrong move , should ensure that the coupling is smooth and

no stairs . Also the interface flange should be straight , and the verticality of the housing should not exceed 1mm, to ensure that the phenomenon will not produce scratching

scraper chain is running, there is conducive to the normal

Operation , to Power Roller Conveyor reduce wear and power consumption.
Ensure head , tail wheel center line level degree promised error within 6mm, and the head, tail wheel and necessary to support rail , and the head , the tail wheel levelness

required school level.
Ascertain the direction of the scraper chain , do not hold against . Scraper chain to ensure proper tightness should not be too tight or too loose. Adjust the tail unit , to

ensure that not less than 50% utilization of the whole of the trip . Electric motor output shaft , gearbox output shaft and the head of the shaft should be parallel to the

conveyor ,

In response to the size of the chain and sprocket two axial offset to within 2mm.
Second, the gap between the blade and adjust the appropriate backplane slot machine This is a relatively important issue , which affects the efficiency of life and

transportation equipment . Clearly, the gap is too small , clinker easily stuck between the blade and the slot machine , slot machine floor scraper or cause damage , even when

severe hair

Health scission accident. Gap is too large , decrease the transmission efficiency . The size of the gap depends on the particle size of the clinker is generally determined by

the following formula :
A> A represents a blade clearance with the bottom of the groove panel D / 2 +5 formula (mm); clinker D represents a maximum particle size (mm).
After calcining kiln clinker cooler through after cooling , hammer crusher after a maximum particle size of 25mm or so, control the gap scraper plate in the bottom slot with

more than 17.5mm , which can reduce the bottom slot plate and scraper wear and prolong its life.
Third, accurate , fair and timely maintenance efforts to strengthen the inspection , examination revealed scraper chain without deformation or rupture , pin the pin on the

falling, should be repaired or replaced.
When the scraper chain loose should be timely adjusted so that the scraper chain often work under proper tension situation , find the topic , in time, to take preventive

measures .
Fourth, the fair design and excellent manufacturing quality carrying member scraper is made ​​of 16Mn steel, welded directly perpendicular to the chain .
Scraper chain is pulling member which is designed for dual- plate chain , after the two steel plates welded into a chain of metal forming rod , then pinned together . Red Star

which is characterized by the use of reliable , manufacturing simple and cheap. In operation, the scraper chain to overcome a lot of friction , bearing

By a great dynamic load and static load , the scraper chain in the manufacturing and welding to be heat treated so as to have high strength , toughness and wear resistance.
Chain plate selection 45Mn2 quenched in the material , hardness HRC62 , the longest life . Pin 45 steel or 40Cr quenched , its quenching hardness HRC38-43.
Strictly control the gap scraper and bottom of the slot machine . Found wandering, timely inspection and timely adjustments. After taking relevant measures , buried scraper

conveyor greatly extended service life , overhaul period of four months from the original extended to 2.5 years , not only reduces the maintenance workload and

In favor of lower production costs , improve their market competitiveness.

Construction machinery from manufacturing to innovation

China 's construction machinery industry did not rely on the garment industry to seek large-scale OEM production of their own development , but also did not rely on the

automotive industry in gravity skatewheel conveyor general as a joint venture to enhance their own strength , but rather out of a technology introduction, digestion, absorption and innovation on the road ,

and gradually mastered its own

Initiative , which for other industries also have a strong reference.
From manufacturing to "wisdom" made
Investment Advisor in the machinery industry researcher Duan Jiaxuan that the development of China's Pipe conveyor construction machinery from the historical point of view , totally dependent

on foreign capital is no future , even in the strength of the gradual growth of today, although there is a large gap between the foreign advanced technology , but also cut Do

not be so anxious to achieve

OEM technology upgrading and took the road to better have strong strength in the time base through mergers and acquisitions , learning and innovation , etc., to absorb

technology, adhere to the road of self-development .
Innovation into the industry rapid development momentum

After 20 years of development, China 's construction machinery industry strength has improved significantly , but in the advanced foreign technology and there is a large gap. If

you embark on the road of OEM production , although you can change in the short term more advanced foreign technology, but the loss of self- brand development .

The lack of independent brands , will be tightly nailed to the low end of the value chain , always walk on the road in low value-added .
Investment Advisor in the Research Director Zhang Yan Lin said that at present , multinational companies to enter the Chinese way of being quietly changed, from the past use of

China's low manufacturing costs , preferential policies to enhance competitiveness factors , leading to the acquisition of a number of Chinese enterprises, OEM cross

Country 's products , and use Chinese company's marketing network and manufacturing capabilities to become a part of its global industrial chain .
Gradually mastered their own initiative
If Chinese enterprises in order to seek quick access to advanced technology and become part of transnational global industrial chain practices often faced with great risk,

although the short term production may increase rapidly, but in key areas , high value-added parts will always be foreign controlled, and

The right to sell and purchase the right one was firmly in control , making it convenient for a profit transfer , in the process , but also Chinese enterprises can only act as a

manufacturing plant 's role only.

Screw conveyor which is mainly used in industry

Go head and tail bearing housing , the hanging bearing sliding bearings , no dust seals , bearings generally use powder metallurgy , transportation of cement used blankets

bearing, shaft and screw spiral conveyor shaft with hanging sliders connections, remove screws, without moving drive means for hanging shaft removal

Order time without moving spiral , do not remove the cover can be lubricated hanging bearings, machine reliability , long life, adaptability, easy installation and maintenance .
Screw Key Features and Applications:
Screw conveyor is widely used in various industries , such as building materials , chemical industry, electric power, metallurgy, coal, grain and other industries, for

horizontal or gravity conveyor inclined conveying powder, granular and small bulk materials such as coal, ash, slag , cement, grain etc. , the material temperature is less than 200 ℃. Screw

machine discomfort

To transport perishable , viscous , easy caking materials

Conveyor injury accident preventive measures

Belt running speed, roller and more, a little careless, often easy to cause injury accident. To prevent injury accident should take the following measures:
1. Transmission part of the belt conveyor nose, tail drum, fluid couplings, etc. must be installed or protective guard railing. Need to cross the bridge should be installed in

the conveyor channel ladder, roller chain conveyor roadway lighting is sufficient.
2. The driver before driving; want to check on the conveyor belt and near the nose and tail, no one really observed only after the issue driving signal. Starts, the first jog

test, indeed no problem to have a formal driving.
3. Driver's clothing should be agile, cuffs, Kujiao, skirts to truss, long hair must be inside the helmet plate. Operation, the roller oiling or be particularly careful when

handling failure, non-direct hand to fiddle with rollers.
4. Conveyor running them, Gravity roller conveyor is strictly prohibited shovels or other tools scrape sticky slime on the drum, or reversal of positive deviation tool belt, otherwise, the most prone

to injury accident.
5. Conveyor ride strictly prohibited. Conveyor stops running, if not cut off the power and put up "Someone working to prohibit driving," the warning signs, prohibition overhaul,

nor stay in the conveyor belt.
6. Roadway conveyor mounted on both sides must be of sufficient width, the conveyor from the stanchions or arch wall distance not less than 0.5 meters, pedestrian side not less

than 0.8 m.
7. To prevent fires, you must use fire-retardant conveyor belt, hydraulic coupling medium must use non-flammable media and require the installation of smoke, temperature

protection device and automatic sprinklers.
8. To ensure the quality of the conveyor installation, the driver should strengthen the maintenance and inspection conveyor, abide by the rules.

Roller parts shall meet the following requirements

a. roller parts and welds should not produce damage and cracks, not loose at mating;
b. roller axial displacement shall not exceed 1.5mm.
6. Idler rollers to 550 r / min rotation, with its waterproof and dustproof performance should meet the vertical conveyor following requirements:

The role of belt conveyor drive roller and type

    The drive pulley belt drive device is powered by the frictional force transmitted to the conveyor member . Typically, the drive roller with steel plate welded structure and

welding structure forms.
    Welded steel roller shaft and flexible conveyor the hub connection between the use of bond can withstand small loads ; cast welding roller shaft and the hub connection between the use of

expansion sets . Avoid the linkage shaft strength weakened , so this structure in the form of cylinders can withstand a greater load , and easy installation and removal. Drum

surface and Telescopic belt conveyor smooth plastic surface in two forms, adhesive side effect is to increase the drive roller and the friction between the belt . Plastic drum with rubber surface and

coated cast two process types , casting plastic rollers and wear thick rubber surface , good quality, but the process is complicated high price ; package plastic drum process is

simple and low cost. Plastic surface drum light adhesive surface, herringbone and diamond-shaped trench trenches three types . When using the herringbone grooved rubber surface

roller , should pay attention to its direction. Herringbone tip should be facing the direction of rotation of the drum , diamond plastic surface for bidirectional transport

roller conveyors . For important occasions preferably vulcanized rubber roller cladding . When there is fire , explosion conditions require , should adopt appropriate measures.

Belt driven structure

   Conveyor motor through the coupling , gear drive or other drive roller rotation drive mechanism , the drive mechanism by means of rollers or other friction between the belt ,

the belt movement. Hunger drive belt roller conveyor conveyor drive unit by way of drive mode can be divided into single-point and multi-point drive two kinds .
    TD75 general fixed belt conveyor drive more than a single point , namely the installation of centralized drive the length of the conveyor at a certain position , usually on

the head office .Power Roller Conveyor  Single-point drive by the number of drive roller can be divided into single drum and double drum drive . For each drum drive can be divided into single- and

multi- electric motor drive right drive . Due to a single motor drive mode most commonly , those who did not specify multi-motor drive, it is a single drive , it is generally

driven approach for single-point call , "single point" word is often omitted .
    Single cylinder , single- motor drives the easiest way , in considering the drive belt should be preferred monocular , single-motor drive mode . In large capacity , long-

distance steel cord conveyor belt is often a multi- motor drive .

Scraper conveyor Scope

    Whether Universal scraper conveyor, scraper or mining are applicable to transport all kinds of massive, granular or powdery bulk materials and good mobility , the weight of

the material , hardness, Gravity roller conveyor temperature and other physical properties , no special requirements, it can be widely used in ore, coal , coke, sand, azurite , grains, salt rock ,

cement , slag and other materials transportation .
    Universal skate roller conveyor scraper conveyor for ground level or angle less than 30 ° occasions transportation of materials . Mining for coal scraper their thickness and inclination were

classified as thin seam scraper for 0.8-1.3m seam thickness face , the face conveyor ordinary slip for 0 ° -25 ° inclination face , and the rest scraper or inclination for

1.3m above 25 ° above the coal seam .
    Scraper conveyor used for conveying small granular and powdered materials can also range between 15 ° angle for inclined conveyor , and therefore on the basis of a single

point of access to materials can also be multi-point access to materials . On the transport of toxic , explosive, high-temperature materials and ease of flying , improve workers

operating conditions and reduce environmental pollution has unique strengths.

Continuous conveyor basic concepts and features

    Continuous conveyor in a continuous manner along a certain line from the loading point to the unloading point uniform conveying of bulk materials and packaged goods into

pieces mechanical device , Pipe conveyor referred to as conveyors.
1, the continuous conveyor equipment advantages:
    1 ) starting, braking fewer , higher speed and the speed and stability, and therefore have a high productivity ;
    2 ) In the same productivity , the light weight, small size, low cost, drive power is small ;
    3 ) transmission mechanism of mechanical parts load is low, the impact of small ;
    4 ) Compact structure, easy to manufacture and repair ;
    5 ) transporting cargo lines fixed , single action , easy to achieve automatic control ;
    6 ) operation, Telescopic conveyor  the load uniformly , the power consumption is almost unchanged .
2 , continuous conveyor disadvantages:
    1 ) only in accordance with a fixed line transmission goods , each model is only suitable for certain types of goods, and are generally used only for transporting small

cargo weight , versatility poor ;
    2 ) most of the continuous conveyor can not automatically pick up , so you must configure the appropriate loading and unloading devices.

Remember points conveyor operation

Belt conveyor in the actual production process, the operator must do the following tasks:
    1 , the operator must be trained by professionals or operate conveyor. The operator must curve conveyor strictly comply with the relevant safety and shift system .
    2 , open the belt checked before transmission parts and wheels , chain plates and safety protection devices shall be solid and reliable.
    3 , check all parts of the lubrication , the lubrication components shall meet the requirements ,vertical conveyor lubrication equipment shall not reached "Five Sets" for filling oil .
    4 , the boot sequence
     ( A ) first opened by the material or equipment.
     ( 2 ) start the conveyor .
     ( 3 ) start feeding device or equipment.
    5, the belt conveyor in operation to feed evenly. Material too easy to plug the outflow outside the machine , resulting in chain plate derailment .
    6 , should always check the tightness of the chain plate , if necessary, can be readily adjusted . Allowed to have uneven force deflection phenomenon.
    7 , conveyor during operation, any failure occurs , immediately stop inspection repair.
    8, the first stop should stop feeding device or devices to be more material on the conveyor net to go , and then stop.
    9 , to keep conveyors clean and hygienic.

Inclined belt conveyor towing improvements

    Inclined belt conveyor for general purpose continuous bulk material handling equipment . As a result of having a corrugated wall and diaphragm belt , it is particularly

suitable for large transmission automated sorting machine angle . The product is widely used in coal, food , building materials, chemicals, utilities and metallurgical industry and other sectors .
    A large angle belt conveyor belt device improved care
Original corrugated sidewall conveyor inclined backhaul segment is used in parallel under ordinary fixed belt conveyor idlers the carrier tape. Easy to use with the tape roller

skirts produce mosaic, Elevator conveyor mosaic will be serious damage to the diaphragm . Often a year or so in the use of conveyors , belt damage has been very serious and must be replaced,

which gives the user great economic losses.
For the above, we return idlers paragraph has been improved with a new device designed to replace care with parallel rollers . Entrusted with the new device consists of two

small rollers, nylon elastic belt and frame composition . Entrusted with the bottom of the device set up two small rollers fixed role , ring nylon strap around two small rollers

, the bracket has a tensioning device, which formed care with devices. The device is mounted on the wall of the tape were two skirts began to entrust the role of tape support

backhaul segment . No direct contact with the skirt small rollers, but in contact with the nylon band , the contact area, embedded into skirts to overcome the phenomenon of the

roller .
The support belt device is unpowered device, nylon belt run is passive, relying on friction effect , with the movement of the corrugated sidewall belts run , and can always

remain in contact with the skirt . Our factory has also developed a device used in conjunction with the support belt pulley duplex tray . By a large guide wheel , a small guide

wheel, fixed shaft and bearing components. Of which the guide wheel , a small guide wheel can be rotated around the axis separately , to overcome the tail left and right two

sides uneven tension caused by stretching the tape two different sides , causing the skirt slippage . Duplex prop shaft pulley fixed at both ends by a bearing fixed . The tape

is running, along with supporting wheels rotate , reduce damage due to friction tape and improve the life of skirts , while also extending the entire corrugated sidewall belt

life.
    Second, the large angle belt conveyor towing device improved use of results
New wavy inclined belt conveyor belt device backhaul segment prop Lianghe sugar Reed has been used in the East branch, Zhefang sugar , sugar back to the Red River slag system in

corrugated sidewall conveyor belt , have achieved good use of effects. After three crop use , wear and tear tape is very small, almost no damage , by the user's praise. The

corrugated sidewall belt conveyor belt device backhaul segment prop , design reasonable, good performance and easy maintenance . Use of the device extends the life of the tape
