Abstract
Centrifugal blasting apparatus comprising a rotatably supported blasting wheel having a plurality of radially extending impeller blades positioned adjacent the periphery of the wheel. The blades are relatively short and have their inner ends spaced a uniform and substantial distance short of the axis of rotation of the wheel so as to define an abrasive supply space between the inner ends of the blades. A tubular member extends into the abrasive supply space for delivering abrasive onto the impeller blades and comprises a main passageway portion having an axis generally parallel to and spaced radially outwardly from the axis of rotation of the blasting wheel and a discharge extension on the inner end of the main portion extending radially outwardly and terminating in a discharge opening adjacent to and in a closely spaced relationship with the inner ends of the blades. Pressurized air propels the abrasive through the tubular member onto the impeller blades.
