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.
