BF series mechanical classifier

working principle: After the materials are evenly fed into the classifier through the feeder, they are dispersed and classified by the classifying wheel in the classifying area. The fine powder that meets the particle size requirements enters the collection system through the grading wheel, and the coarse powder is thrown to the cylinder wall and moves down to the secondary air inlet, where the material is washed by the updraft generated by the secondary air entering the machine body. The coarse and fine powder are separated again, the fine powder enters the classification zone and is classified by the classification wheel, and the coarse powder is discharged from the discharge port at the lower part of the classifier.
