Abstract

A mechanized reclaiming system for separating ferrous and non-ferrous metals from other materials derived from crushed and shredded automobiles employing a pair of conveyors mounted in a vertical array with the top one separating under vibratory action the small particles of material from the larger particles with the small particles going to a processing tower with this material being processed again into lighter and heavier materials. The lighter material is separated further by centrifugal action while the heavier material is separated into magnetic and non-magnetic material by magnetic means with the non-magnetic material being further separated into light and heavier material through water treatment in a rotating drum.
