The rotor rotates at a high speed and generates a large amount of air vortex. Under the dual action of air vortex and centrifugal force, the materials not only collide with each other, but also shear and grind between the rotor and the stator to achieve ultra-fine crushing of the materials. The impact mill must be fixed in cement.
