ABSTRACT:
An apparatus for reclaiming material primarily used in the fabrication of foundry molds is provided in which the sand in the form of large chunks of mold is introduced into a vibrating conveyor and carried initially to a rotary hammer assembly. The chunks are chopped into finer pieces which fall back into the conveyor and are moved into a vibrating drum assembly which causes the pieces to self-abrade into particles. When the particles reach a predetermined size, they leave the drum through a perforated gate means and fall back into the conveyor which carries the particles to a vibrating screen. Particles passing through the screen are then removed for further processing.
