Title: Rotary door blast chamber

Abstract: A blast chamber is disclosed which employs a rotary cylinder having openings therein for permitting the entry and exit of a part to be blast cleaned. The cylinder is enclosed in a housing in such a manner that when the openings through the housing and cylinder are aligned, a part to be cleaned can enter or exit the chamber. When the openings are misaligned, the chamber is sealed to prevent the escape of particulate during the blast process. The invention is suitable for use with a conveyor system for substantially continuous operation.
