What are the causes of cracks in PVC conveyor belts?

- Apr 19, 2019-

In the industrial belt transmission, many people may encounter such problems. Among them, the PVC conveyor belt is often cracked. This is a problem. Today, Xiaobian will tell you about the cause of PVC conveyor belt cracking. I hope it will be useful to everyone.


         Why is the PVC conveyor belt cracked?


       1. Due to the limitation of space size, PVC conveyor belts have many bending times.


       Second, PVC conveyor belt joints have been repeated more than twice for various reasons.


       Third, the diameter of the reversing drum is small, and the bending stress of the PVC conveyor belt is large.

Fourth, the PVC conveyor belt joint quality is poor, especially a belt with more than three joints, the tensile strength is significantly reduced, or the canvas layer is cut or polished during the bonding, where the strength is reduced.

       5. For the reversible conveyor, since it can only be in one direction when it is lapped up and down, it is easy to be scratched by the sharp corners of the sweeper, unloader and other equipment on the belt.


       Sixth, the conveyor has a short working cycle, frequent starting, and large instantaneous tension.


       The reason for the crack of the PVC conveyor belt is first introduced to everyone here. If you have more questions, please feel free to contact us.
