ABSTRACT:
A magnetic separator for particulates containing prime material and ferrous particles includes a housing having a removable cover having a central throated inlet along its length. A pair of vertically and laterally displaced hollow metallic rolls are journaled upon the end walls and extend the length of the housing, and enclose an elongated semi-cylindrical permanent magnet within each roll, the magnets being of opposite polarity. A pair of elongated, vertically and laterally displaced flow control dampers extend along the length of the housing and are pivotally mounted thereon and define with the inlet and rolls a vertical first feed path for the particulates. A first elongated hopper underlies the first flow path and has an elongated outlet overlying a first conveyor for receiving and delivering prime materials from the housing. Second and third elongated hoppers are arranged upon opposite sides of the first hopper under the rolls respectively. Additional conveyors underlie the second and third hoppers for delivering ferrous particles outwardly of the housing. Elongated opposed roll shaft receiving slots are formed in the end walls to facilitate roll replacement.
