ABSTRACT:
A material separator separates non-magnetic particulate material into components having differing electrical conductivities and comprises a support frame, a drum rotatably journaled with respect to the support frame, a magnetic assembly in the drum interior and a drive system. The drum's sidewall is cylindrically shaped and the magnetic assembly incudes longitudinally extending magnetic arrays, each angularly spaced from one another and rotatably journaled on a respective array axis that is radially spaced from the drum axis. The magnetic arrays include opposite magnetic poles located along a rotational surface such that when they rotate, an oscillating magnetic field is induced through the drum's sidewall. The drive system rotates the magnetic arrays and the drum so that particulate material placed on an outer surface of the drum sidewall is subjected to the oscillating magnetic field whereby components having different electrical conductivities are discharged with differing discharge trajectories. A methodology for separating nonmagnetic particulate material is also provided.
