PCT No. PCT/SE96/01276 Sec. 371 Date May 11, 1998 Sec. 102(e) Date May 11, 1998 PCT Filed Oct. 9, 1996 PCT Pub. No. WO97/13582 PCT Pub. Date Apr. 17, 1997A device for separating metallic and non-metallic materials via an inclined conveyor belt and vibrating plate feed. Feed material is dropped from the feed plate onto the inclined portion of the conveyor. Magnetic material adheres to the inclined belt by attraction to a magnetic plate spaced such that the belt interposes between the magnetic plate and the materials to be separated. Non-metallic materials fall down the incline into a collection area. The device further includes a second magnetic plate, after the first, oriented to diverge from the belt in the direction of conveyance to provide a uniform, attenuating magnetic flux.
