Belt Conveyor The main technical parameters

     Leather belt with a conveying capacity, simple structure, easy maintenance, standard parts, etc., are widely used in mining, metallurgy, coal and other industries, used to

transport
Loose materials or items, according to the transport process requirements, can be a single conveyor can also be composed of multiple components or with other equipment to form

horizontal or inclined conveyor system to meet the
Different types of operating line layout needs for conveying bulk density less than 1.67 / t / cubic meter, easy to dig a powder, granular, small block of low-abrasive materials

and bags
Loaded materials such as coal, gravel, sand, cement, fertilizer, food and so on. Sent material temperature is less than 60 ℃. Its captain and assembly forms can be determined Turn conveyor

according to user requirements, transmission can
Power roller, can also be used with the drive frame driving means.

       Belt conveyor used can be divided into: ordinary canvas core conveyor belt, high strength steel cord belt transmission machine, run under full proof belt conveyor,

flame-type belt conveyor,
Two-speed dual op-belt conveyor, reversible mobile belt conveyors, belt conveyor and so cold.

      Belt conveyor mainly from the rack, conveyor belt, belt roller, tensioning devices, drives and other components.

            Belt conveyor belts common faults

  A belt conveyor belt deviation runtime is the most common faults.

         To address such failures is important to note the dimensional accuracy of installation and daily maintenance. There are several reasons for deviation, to be based on

the difference between handling different reasons.
       1 Adjust the belt conveyor idlers bearing belt in the middle of the entire belt conveyor idlers deviation, adjust the position to adjust the deviation; during manufacture

roller group two
Side mounting holes are worked into holes for adjustment. The specific method is biased belt which side, which side idlers forward direction toward the belt forward, or the

other side after
Shift.

      2 Install aligning roller group aligning roller group has many types such as an intermediate shaft type, four-link, vertical roller type, etc. The principle is the use of

block or roller direction in the horizontal plane
Moving block or automatically generate horizontal thrust to the heart of the belt to adjust the belt deviation purposes. Average total length of the belt conveyor or belt

conveyor shorter run-time bi-mining
With this method more reasonable, because the shorter belt conveyors easier deviation and not easy to adjust. And long belt conveyor is best not to use this method, because

self-aligning roller group
The life of the belt use would have some impact.

         3 Adjust the drive pulley and the driven pulley and bend pulley position adjustment bend pulley belt deviation adjustment is an important part. Because a belt conveyor

with at least two
To five rollers, all the rollers must be perpendicular to the installation location of the longitudinal direction of the conveyor belt center line, if the skew is too large

deviation inevitable. Adjustment Method and its care
Rollers similar. For the head drum as the drum belt deviation to the right, the right of the bearing should be moved forward, the belt deviation to the left of the drum, the

left of the bearing seat
Should be moved forward, the corresponding can also be moved left or right rear bearing housings after the shift. Rear roller adjustment method and the head drum opposite. After

repeated adjustment
Until the belt adjusted to the ideal position. Adjust the drive or bend pulley in the best pre-install its exact location.

       4 tension belt tension adjustment at the adjustment at the conveyor belt deviation adjustment a very important part. Hammer tension bend pulley at the top two in addition

to
Other than perpendicular to the longitudinal direction of the belt should be perpendicular to the vertical line of gravity, which is to ensure its axis horizontal centerline.

Tensioning screw or hydraulic cylinders with tension, the tension roller in the two axes
Meanwhile seat pan should be to ensure that the drum axis and perpendicular to the longitudinal direction of the belt. Specific method of adjusting the belt deviation adjustment

of the drum at similar.

 5 reprinted point blanking position on the belt deviation of reproduced material blanking at the point position on the belt deviation has a very big impact, especially in the

two horizontal belt conveyor
When projected into a plane perpendicular to a greater impact. Usually reproduced points should be considered down two belt conveyor relative height. The relative height of the

lower, the greater the horizontal velocity component materials,
On the lower side of the belt greater impact, but the material is difficult to center. The cross section of the material on the belt deflection, resulting belt deviation. If the

material is biased to the right
Side, the belt deviation to the left, and vice versa. In the design process should be possible to increase the relative height of two belt conveyor. In space-constrained mobile

bulk material handling machinery
Upper and lower funnel, guide trough and other pieces of form and size should be seriously considered. General guidance for the width of the trough belt width should be about

two-thirds more appropriate. To reduce or
Avoid belt deviation increase blocking plate blocking materials, changing direction and position of the whereabouts of the material.

      6-way running conveyor belt deviation adjustment bidirectional running belt conveyor belt deviation adjustment than the one-way conveyor belt deviation relative to the

adjustment difficulties Xu
More specific adjustments should be adjusted first in one direction, and then adjust the other direction. Adjust the belt to carefully observe the movement direction of the

relationship with the deviation trend, one by one into the
To adjust. Emphasis should be placed on the drive pulley and bend pulley adjustments, followed by the adjustment of the roller and the material blanking point adjustment. Also

note that when the belt vulcanized joints
The longitudinal direction of the belt section should be the force evenly in the use of both sides of the chain traction force equal as possible.

        Second, the belt conveyor material handling scattered

     Caesar conveyor belt material is a common problem, the reasons are multi-faceted. But the focus is to strengthen the daily care and maintenance.

     1 reprint reprint scattering material at the point of the point spread mainly in the fall feed hopper, guide trough, etc.. If severe overload belt conveyors, belt conveyors

guide trough gauge rubber skirt
Board is damaged, steel guide trough at design time far away from the belt so that the material is relatively long rubber apron out of guide trough. The situation can be

transported in the control capacity, enhance maintenance
Be resolved.

 (2) when the concave section of the belt material spreading vacant belt concave segment interval when the radius of curvature smaller concave segment will generate vacant belt,

then the belt into a trough situation changes, because the belt
Has left the trough idlers, generally groove angle becomes smaller, so that part of the material spread out. Therefore, at the design stage should be possible to use a larger

radius of curvature of the concave section to prevent this
Type of situation from occurring. If the mobile mechanical ship loader, stacker-reclaimer device in order to shorten the trailer and the concave section designed here no arc

transition interval, when the belt width selection
Smaller degree than the material easier to spread.

      3 the scattering material deviation belt deviation because of the scattering material is running two belt edge height changes, high side, the other side is low, the

material from a low
Side spreading out, processing method is to adjust the belt deviation.
