troughing angle of belt conveyor

Excessive troughing causes conveyor belt damage | Martin ...

2022-2-10 · Exceeding its troughing capability can result in damage to the belt. Exceeding the maximum trough angle of a particular belt can cause the belt to permanently deform into a cupped position. Cupping can make a belt difficult to seal, difficult to clean, and almost impossible to track. As the cupping increases, the surface contact between the ...
