Compared to the known types of feeders (plate, reciprocating, apron, belt) vibrating feeders, due to their specific interaction with the processed medium, provide a more stable flow of material through the hopper mouth, prevent sticking and vaulting, and favorably differ in terms of power consumption, reliability, abrasive wear and, often, metal consumption. Vibrating feeders make it possible to combine the transportation of material along the chute with its screening and dewatering.
