Components of a Standard Belt Conveyor - Martin Eng

A belt conveyor is a relatively simple piece of equipment. The belt is supported along the top (carrying) side with flat or troughing rollers called idlers. Troughing rollers form the belt into a U-shape that increases the cargo capacity of the conveyor. On the bottom (return) side of the conveyor, where the belt returns to the loading point, the belt is supported with return idlers.
