Mill
 This invention provides a non-ball mill, which makes the material to circulate at high speed within the mill so as to crush the material by means of the impact and friction among the material themselves. The mill includes base, motor, body for forming milling chamber, return funnel, and outlet port. A shaft driven by a motor penetrates the milling chamber and is provided with a rotating assembly for rotating the material within the milling chamber. The milling chamber consists of an upper chamber and a lower chamber formed respectively by pyramidal upper and lower body, so as to make the material to circulate within the milling chamber. A separating chamber is provided at the upper portion of the upper chamber, and the separator mounted on the shaft output the material of fine size to the outlet port. The mill has the advantageous of less energy consumption, no consumption of steel, light weight, high productivity, reduced wearing rate, small noise and vibration. The mill may be operated in either wet milling or dry milling manner, and combine crushing and separating operation together within a single device.
