<p>An improved particle blast cleaning apparatus and process featuring sublimable pellets as the particulate media is described as having a source of sublimable pellets, a housing (48) defining an internal cavity (46) having spaced pellet receiving (42) and discharge (68) stations, and a radial transport rotor (62) for transporting the pellets from the receiving station to the discharge station. The radial transport rotor further includes a plurality of transport cavities (64) each being formed in the circumferential surface of the radial transport rotor to receive the pellets for radial transport between the receiving and discharge station. The receiving station is in communication with the source of sublimable pellets, and has a mechanically assisted (132) flow of the pellets to the transport cavities. Also included is a discharge nozzle and a high pressure transport gas source for conveying the pellets from the discharge station to the discharge nozzle.</p> |
