Abstract
Materials separator apparatus for segregating electrically conductive particles having a wide range of sizes from a stream of commingled materials. The apparatus includes a material feeder device disposed for directing the commingled particles into a stream. A spatially alternating, steady-state array of juxtaposed, oppositely directed magnetic fields of varying widths is established adjacent the stream. As the materials pass through the magnetic fields, forces exerted on the electrically conductive particles cause lateral deflection of these particles from the stream thereby providing the desired separation. Because the widths of the magnetic fields vary over a wide range, the apparatus provides effective separation of a wide range of sizes of electrically conductive particles.
