ABSTRACT:
A blast surface treating machine utilizes a control cage featuring an inlet and an outlet that is positioned with its outlet within the central space of the machine blast wheel. A hopper supplies particulate material to the control cage inlet. A rotating screw conveyor transports the particulate material through the control cage. The screw conveyor also forces the particulate material out of the control cage outlet where it is picked up by the rotating blast wheel. The control cage is oscillated about the axis of the blast wheel to provide a widened blast pattern upon the surface being treated. The blast wheel, blast wheel housing, control cage and screw conveyor are constructed of manganese or hardened steel to provide the an anti-shattering construction in the event that a bolt or other foreign object falls into the hopper.
