FIELD: shot-blasting of cylindrical surfaces. SUBSTANCE: working mixture is applied on surface to be treated by means of device shaped as turbine with nozzle assembly forming circular disc-like tool. Working mixture is supplied with use of paired electric motor and generator with rotors fitted rigidly on turbine rotated by working mixture. Steel balls are used as working mixture and disc-like tool is represented by shot-flare tool. Provision is made for use of cavitation mixer and cavitation tool. EFFECT: intensified shot flow. 5 cl, 2 dwg
