The apparatus includes a device or features for removing from the surface the particulate material and debris generated by the treating process. The removing features include a magnetic drum for attracting ferromagnetic material, a vacuum packup for removing nonmagnetic material, and a plurality of air jets for positioning and lifting the material to increase the efficiency of the recovery process. The recovered material is separated according to content and the particulate is recycled for reuse.
