Belt Conveyor : Do You Know Why There is Conveyor Belt Deviation Phenomenon?

Belt conveyor is a common conveying equipment widely used for metallurgy, chemical, electric power, coal, mining, port etc. In the process operation, conveyor belt deviation happens a lot. Here PK Machinery will analyze the reason as follows:
1.there is attached object on the surface of pulley or roller .
2.both driving pulley and the turnabout pulley have external surface error in manufacturing .
3.the head driving pulley is not parallel with tail pulley.

4.the diameter of driving pulley and the tail pulley is different.
5.the center line of driving pulley and tail pulley is not vertical to the conveyor center line.

6.the feeding position is not straight.
7.pulley center is not in the center line of conveyor.
8.roller installation is not straight.
9.bad frame rigidity which will easily lead to the deformation.
10.unstaight conveyor belt joint and belt aging metamorphism will cause deviation on both sides.
11.unilateral bearing rotation is not flexible, or it is stained with sundry.
12.abrasion condition on both sides of guide pulley is different .
13.deviation adjusting device damages and doesn’t work well.

14. the pulley wrapped with belt is not parallel with the transmission drum.
15.conveyor belt borders on both sides of the centerline are not overlapped, or conveyor belt edges get worn seriously.
16.feeder, discharger and sweeper have installation error.
17.abrasion condition of pulley two ends is different.
18.conveyor belt take-up device doesn’t have enough tension.
19.the layout of feeding direction and conveyor height is not reasonable.
20.roller support gets worn and deflected seriously.
