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.
