Conveyor belt damage comes in a variety of types

Edge damage is usually seen as frayed edges on one or both sides of the belt, but given time can wear away at the width of the belt to the point where it reduces the conveyor system's overall capacity. Damage to the belt edge is a sign of the belt mistracking into the conveyor structure. The leading cause of belt-edge damage is belt ...
