摘要

FIELD: mechanical engineering. SUBSTANCE: this relates to shot-blasting treatment of articles which are subjected to subsequent plasma jet spraying. Abrasive-blasting apparatus has body which carries replaceable head-piece with partition. Located between body and head-piece is screen, and locate below screen in body is filter. Replaceable head-piece at one side of partition incorporates mixing chamber, and at other side it incorporates reservoir for abrasive matter. Accommodated in body are diffuser and compressed air delivery unit which is made in the form of shaft with two rows of blades.
