Fig. 6.1.1. A flat belt conveyor with drive control
(b) Troughed Belt Conveyor: In this conveyor, comparatively wide flat belt is supported on troughed carrying rollers or shaped supporting surface so that the two edges of the active side of the belt are elevated from the middle part to form a trough. This provides a greater carrying capacity than a flat belt of equal width for conveying bulk materials or those materials which would slide off flat belts. These conveyors are used in handling bulk materials of different classes. The return side of the belt is generally kept flat supported on cylindrical rollers.
