Ten reasons for belt deviation of belt conveyor

Belt deviation refers to Belt conveyor In the process of operation, the belt center line deviates from the conveyor center line. This fault is a common fault in the process of material transportation, which will seriously affect the normal production of the conveyor. Red Star Machine Through the research, it is found that the specific reasons for the deviation of conveyor belt mainly include the following ten aspects.


1. The improper installation of the carrier roller group makes the perpendicularity error between the installation position and the conveyor center line, which leads to the deviation of the conveyor belt.

2. If the unloading position at the transfer point is improper or the fuselage is not straight, an impact force perpendicular to its running direction will be produced on the conveyor belt, which will lead to the deviation of the conveyor belt. In the design and manufacture, the width of the guide groove should be designed to be about 2 / 3 of the width of the conveyor belt, or the deviation of the conveyor belt can be reduced or avoided by adding a baffle plate.

3. If Layout of tension device of belt conveyor If the tension is insufficient, the stability of the conveyor belt will become worse, and it is easy to be disturbed by external forces, and even slip. In practical application, counterweight can be properly added to avoid deformation of conveyor belt.

4. The improper installation of the driving roller and the reversing roller leads to the inconsistent tightness of the conveyor belt on both sides of the drum, resulting in the belt deviation to the loose side. If the conveyor belt deviates, the position of the driving roller and the reversing roller can be adjusted properly.

5. When there are machining errors, uneven wear or sticking materials on the outer surface of the drum, the diameter of the roller becomes inconsistent, which will cause the conveyor belt to deviate to the side with larger diameter. Therefore, in the process of equipment operation, the drum surface should be cleaned in time, and the roller with uneven wear should be replaced.

6. The diameter of both ends of transmission drum or tail drum is not equal.

7. The head drive drum is not parallel to the tail drum.

8. The center line of transmission drum and tail drum shaft is not vertical to the center line of fuselage.

9. The grooved or flat idlers are out of alignment.

10. The joint of conveyor belt is not correct or aging deterioration, resulting in inconsistent tightness on both sides of the conveyor belt.
