ABSTRACT:
This invention is directed to an apparatus for subjecting an article to shot blasting under cryogenic conditions which comprises a housing encompassing an entry station, an impacting station and an exit station. In connection with the housing, there are means provided for transporting an article to be shot blasted sequentially from the entry station, through the impacting station, and then to the station. A connection is made to the housing permitting the introduction of a cryogen into the impacting station thereby maintaining such station at a cryogenic temperature. The apparatus also has a means for directing media at a high velocity so as to impact upon an article to be treated while such article is being transported through the impacting station. The apparatus of the invention also functions to rotate the article while it is being transported through the impacting station, thereby permitting the stream of media to contact all critical portions of the article.
