The bevel gear transmits in a whole and drives the main shaft, who is connected with the roller hanger in the top. There are grinding rollers installed in the hangers and forming a swing support. The rollers rotate not just around the main shaft, but also around the grinding ring, besides, rollers can rotate to itself as well because of friction. Shovels are installed at the bottom end of hanger; when shovels rotate together with rollers, materials will be fed into space between rollers and ring to form a material layer, which will be grinded due to centrifugal force. The classifier drives the blades in the rotary table through the speed motor to classify the powder.
