Even though a belt conveyor is carefully designed, material spillage from the carrying side of the belt may occur at the loading point and elsewhere along the belt conveyor. There are many factors that can lead to the spillage, such as the material off-center loading at the transfer point and the belt mistracking along the conveying route.

The primary function of idler rolls in a belt conveyor system is to support the conveyor belt along its length. Predicting the cumulative resistance of idler rolls is vitally important in calculating the belt tension and therefore power requirements of a system, particularly on long overland conveyors where there are typically more than one thousand idler rolls per kilometer of belt. The ...
