Abstract
A magnetic separator for removing ferrous or other magnetic contaminants from loose, non-magnetic materials comprising a bipartite assembly having two sections, which when joined, define a flow passage having an inlet for receiving material to be processed and an outlet for processed material. Magnetic elements in the form of prongs arranged in a plurality of assemblies, associated with each section, travel through the flow passage in an inter-digitated relationship and capture the magnetic substances in the material. The captured contaminants are released at discharge stations spaced from the outlet, where the prongs are demagnetized. Any material not released, is cleaned from the prong assemblies by brushes located at a cleaning station. The prongs are magnetized by a plurality of magnet assemblies that are transported by a conveyor in synchronism and juxtaposed relation with, the prong assemblies for a portion of their travel. The path of the magnet conveyor diverges from the prong conveyor to achieve demagnetization of the prongs at predetermined locations.
