The high-shear emulsifier uses the rotor to rotate at high speed and steadily to form high-frequency, strong circumferential tangential velocity, angular velocity and other comprehensive kinetic energy efficiency; under the action of the stator, the stator and rotor are in a reasonably narrow gap. The formation of strong, reciprocating hydraulic shear, friction, centrifugal extrusion, fluid collision and other comprehensive effects, the material cyclically reciprocates in the container during the above working process, and finally the product is obtained.
