DESIGN AND FABRICATION OF A MILL PULVERIZER
The pulverized material is carried out of the mill by the flow of air moving through it. The size of the pulverized particles released from the grinding section of the mill is determined by a classifier separator. If the refined grain is fine enough to be picked up by the air, it is carried through the classifier.
