FIELD: machine building.
SUBSTANCE: proposed machine comprises cylindrical housing, initial material feed pipe, material discharge pipe and rotor drive. Initial material distributor composed of fixed cone is arranged directly above the rotor. Circular flanges are arranged at housing sidewall while fine dusty fraction discharge pipe is arranged at housing top section. Rotor fitted on the shaft in said housing is shaped to cylinder in height equal to rub-off zone and equipped with radial blades. It includes industrial blower is communicated with pipe discharging the fine dusty fraction along with airflow. Initial material feed pipe is arranged directly above initial material distributor. Finished product discharge pipe is arranged at housing bottom section.
EFFECT: higher efficiency of rubbing-off and separation.
