FIELD: pneumo-mechanical grinding and homogenization of dry loose materials of medium and small strength. SUBSTANCE: proposed rotary centrifugal grinder has housing consisting of cylindrical and tore-shaped parts. Rotor located in cylindrical part includes cutting blade, screw attachment, detachable working member of conical attachment and discharge impeller. Screw attachment and detachable working member are embraced at clearance by cogged envelope rigidly secured on housing; conical attachment is embraced at clearance by confuser ring rigidly secured on inner surface of housing. Mixer is made in form of activating wheel secured on rotor shaft. Rigidly secured on outer lateral surface of activating ring are plate blades secured radially; tore-shaped chamber is provided with transversal partition having cut separating the mixing chamber into suction and discharge passages. EFFECT: enhanced efficiency of grinding; reduced specific power requirements. 4 cl, 4 dwg
