This machine is a vertical shaft reflection type pulverizer, which can complete two processing processes of micro-pulverization and particle sorting at the same time. The pulverizer is composed of a moving disc and a gear ring. Through the high-speed rotation of the moving disc with special shape, the material particles are repeatedly squeezed, collided and sheared between the moving disc and the stationary gear ring for many times, thus achieving pulverization. The quantitative feeding system conveys the material to the pulverization chamber, the material is impacted and sheared between the high-speed rotating rotor and the stator of the tooth lining. The crushed material enters the classification area under the drive of the air flow. The qualified material is collected by the cyclone and the dust collector, and the unqualified material is returned to the crushing area for crushing.
