Abstract
Apparatus for separating non-magnetic metals to permit recovery, for example, of aluminium and other non-magnetic metals mixed with materials having other compositions. The mix of materials are vibrationally conveyed in a first direction by a vibration feeder and a deflecting force in a second perpendicular direction is exerted on the non-magnetic metals by moving magnetic fields produced by a plurality of linear motors. The apparatus includes means for controlling the longitudinal tilt and the transverse inclination to optimize the separations achieved with different mixes of materials.
Claims10
A linear motor-type, non-magnetic metal separating apparatus comprising:
- a vibration feeder provided with a vibrating deck and means for causing vibration and defining a vibrating direction of conveyance;
- at least two linear motors disposed on the vibrating deck of said vibration feeder so that the advancing directions of the forces provided to non-magnetic metals to be separated by the moving magnetic fields of said linear motors are approximately parallel to one another and perpendicular to the vibratory direction of the conveyance;
- and
- a trough disposed as a cover for said linear motors and adapted to be vibrated by said vibration feeder from the underside thereof, said trough defining a series of steps.
