The machine is widely used in many fields, such as medicine, chemical industry agricultural chemicals, viands and foodstuffs. This machine trough the high-speed relative motion of movable fluted disc and fixed fluted disc, are pulverized by the multiple actions of collision, cutting, friction of teeth and the mutual collision of materials themselves. The machine is simple and sold in structure, and steady in motion with a good result of pulverizing. The pulverized materials is ejected out of the chamber of the main frame, the different fineness of pulverized products can be attained by changing screen meshes of different apertures.
