A feeder is a material handling equipment used to regulate the flow of a bulk material from a bin or hopper. Feeders are often used in conjunction with other types of material handling equipment, like conveyors, crushers, dryers, grinders, blenders, and mixers. Several types of feeders can be used in a crushing/process system.
