ABSTRACT:
In accordance with the teachings of the present invention, an abrasive blast wheel is assembled for cleaning work pieces with abrasive materials. The blast wheel assembly is simplified by securing the blades about the impeller by inserting them into slots in a blade supporting wheel and retaining them therein with a retaining ring that extends over the outer edge of the wheel. Removal and subsequent replacement of the blades is thus simplified because all of the blades may be removed simultaneously by merely removing the retaining ring.
