ABSTRACT:
A blast media recovery system is provided that recycles reusable blasting media from spent blasting materials. The system includes several different separators which classify the recovered materials by either specific gravity or size. After the materials have been classified by size and the low density materials have been removed, the bulk recycled materials are directed towards a dense particle separator that is arranged to separate any high density materials from the usable blasting media. The dense particle separator includes a frame having a plenum coupled thereto. A porous stone is placed within the plenum and the recycled materials to be cleaned are delivered into the plenum over the top surface of the porous stone. Compressed air is then passed into the plenum through the porous stone to form a fluidized bed. As more material enters the plenum, the lower density materials (i.e. the reusable blasting media) pile over the higher density materials and spill from the plenum into a media chute. The heavier materials retained within the plenum are periodically emptied. The system is arranged to automatically allow continuous recycling of the blasting media.
