ABSTRACT:
A recyclable abrasive blasting system for blasting abrasive against a surface to be cleaned and for recovering such abrasive which has been blasted, comprising a storage hopper for containing abrasive, blast pots which receive abrasive and deliver it to a blasting hose wherein abrasive is propelled against a surface, an autodump tank including an inlet for receiving particles resulting from blasting, such particles comprising trash, debris, dust and abrasive, a screen for separating trash and debris from the particles, an airwash for separating dust from said particles, and valves for metering the amount of particles traveling therethrough, a classifier includes a first auger and a plurality of augers formed by screens having spiral members thereon, the plurality of augers surrounding the first auger and in rotating cooperation therewith, whereby the screens classify debris from abrasive such that it may be routed outside of the classifier, whereby an airwash takes place and wherein any remaining particles travel to a particle separator having accumulating plates in cooperation with a hinged rod for creating a curtain of particles, and a blower for separating abrasive from debris in the curtain of particles and routing the abrasive to be stored in a storage hopper, wherein a last airwash takes place on the remaining dust and debris, the debris and dust thus separated and routed to separate outlets from the housing of the particle separator.
