Feeders and Vibrating Conveyors

Abstract

Feeders are short conveyors or other devices used to take material from the bottoms of bins, silos, or hoppers, and to transfer them to other types of conveyors. They are used to regulate the flow of material to crushers, screens, conveyors, or other equipment. Single reciprocating feeders give pulsating flow. Twin units that discharge alternately are an improvement. Apron feeders give a more continuous flow and distribute the lumps in the flow. Electromechanical and electromagnetic vibrating feeders can be equipped to screen the fines ahead of the crusher, and all have easily adjusted feed rate. Feeders must be wired to stop promptly when the crusher stops.
