Abstract: A rotor assembly is provided for blast processing. The rotor assembly includes multiple lofting elements to create a vortex to loft particulate material to be used to process a target, and multiple impelling elements to project the particulate material toward the target. The rotor assembly is enclosed within an operating chamber that has a target area into which the particulate material is projected to strike the target. There may further be angled deflectors at the opening to direct particulate material back toward the rotor assembly to use the material for further processing. Certain components are easily adjustable for different sizes and shapes of target. The action of the rotor assembly enables the use of up to 100% pure grit for entire cleaning processes, and provides single pass hook profile on any common material surface.

Abstract: An abrasive cleaning apparatus comprising a housing defining a substantially closed operating chamber with a pair of rotating impellers therein. The abrasive cleaning material is directed into the chamber where the blades of the impellers contact the particulate cleaning material and throw the material through an open front area of the chamber against the surface to be cleaned. At the front of the housing is a yielding perimeter portion which provides a seal against the surface which is being cleaned. The waste material removed from the surface being cleaned is drawn through an outlet port to a cyclone type separating chamber where the abrasive particulate material is separated and directed back to the operating chamber, and the waste material is delivered to a waste location. The abrasive material in the housing remains in the housing and is directed repeatedly against the surface to be cleaned.
