By the relative movement of the different geometric shaped stator and rotor under high-speed rotation, the material to be processed enters into the mill under the action of the Dead weight and air pressure force and centrifugal force and of the composite force, such as the strong shearing, rubbing, impact, high-frequency vibration when the material is through the annular variable gap, and then the material will be effec- tively dispersed, pulverized, emulsified, admixture, thereby the product with the satisfactory size and the quality will be fulfilled.
