Abstract

A blast cleaning machine for blast cleaning parts comprising a main frame, a housing supported on the main frame, and a barrel assembly rotatably supported in the housing for oscillatory movements therein between loading, blasting and discharge positions. The barrel assembly has an annular side wall provided with relatively inclined sections that cooperate with relatively inclined surface sections at the bottom of the barrel to provide for a continuous tumbling and flowing of parts in the barrel across a stream of shot projected into the open end of the barrel by a conventional impeller assembly. This action of the parts assures a full cleaning of all of the parts in the barrel in a relatively short time.
