FIELD: production processes.
SUBSTANCE: invention refers to devices of abrasive jet treatment of surface of various materials. Device includes tubular housing with branch pipes, which is provided with widened cone-shaped part, air supply inlet hole and outlet hole, channel for supplying an abrasive and/or liquid with outlet nozzle on the end, central channel for supply of air jet with outlet nozzle, two swirlers and channels supplying chemical components and/or water. Channel for supply of abrasive and/or liquid with outlet nozzle on the end is installed in housing and located coaxially to inlet air supply hole. One of the above swirlers is located in inlet air supply hole, and the other one - in outlet housing hole. Channels supplying chemical components and/or water are made on the basis that component jets are formed with possibility of parts of the above jets being crossed at one point of housing axis. Outlet housing hole, outlet nozzle of channel for supplying abrasive and/or liquid and outlet nozzle of central air supply channel are located coaxially and protrude to one overall housing plane.
EFFECT: reducing energy consumption, increasing economy and effectiveness of device, increasing efficiency and wear resistance.
