A method of using a recyclable abrasive blasting system for blasting abrasive against a surface to be cleaned and for recovering such abrasive, comprising a storage hopper for containing abrasive, blast pots which receive abrasive and deliver it to a blasting hose, 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 values for metering the amount of particles traveling there-through, 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.
