ABSTRACT:
Disclosed is an improved centrifugal blasting apparatus for the blast cleaning or shot peening treatment of a selected surface of an object to be treated by throwing pulverized abrasive material onto the surface. Its wheel casing has an elongated slot to permit pulverized abrasive material to pass therethrough and scatter through the air with centrifugal force, which is given by the blades of the rotary blade wheel. The inlet suction conduit extends from the blasting cabinet to the wheel casing, and the outlet suction conduit extends from the wheel casing to an associated vacuum pump. The abrasive material storage or collector is provided in the inlet suction conduit, thus making up an abrasive material circulating loop. The apparatus uses no force of gravity to supply pulverized abrasive material to its rotary blade wheel, and therefore, the positioning of the rotary blade wheel is not limited with regard to availableness of the force of gravity. It requires neither air-tight ejector nor screw conveyers or bucket elevators, and accordingly its weight and size can be reduced substantially.
