ABSTRACT:
A cryogen shot blast system is provided which includes a sealed cryogenic chamber and a barrel which is supported within the cryogenic chamber and is rotatable about a longitudinal axis. The barrel is pivotally mounted so that the longitudinal axis of the barrel has a variable angle of inclination. The cryogenic chamber includes a drum portion and a generally hemispherically-shaped dome portion which seals an open end of the drum portion. The cryogenic chamber is jointed such that the barrel and a portion of the cryogenic chamber can rotate between a loading position wherein work pieces can be loaded into the barrel and an operating position wherein the barrel is sealed within the cryogenic chamber. A throwing wheel propels particulate media into the barrel to impact work pieces. A nozzle injects the particulate media at different orientations within the throwing wheel to vary the direction of flow of particulate media from the throwing wheel.
