1、 Working principle

After the materials are roughly broken, they will enter the ultra-fine ball mill through the lifting and conveying equipment. The grinding medium in the mill will impact crush and grind the materials with the energy obtained during the rotation of the mill. The crushed materials will enter the self split micro powder classifier through the discharge bin for classification, so as to realize the separation of coarse and fine powder. The qualified fine powder will be collected by the collector, and the coarse particles will enter the ball mill again from the lower end of the classifier for crushing, The purified gas is discharged by the induced draft fan.
