Coal grinding is performed by quickly rotating rotor by means of impact and grinding effect. Milled coal is removed from grinding area by drying agent to separator where the segregation of large-sized coal fractions from air-and-coal mixture and their return for finish grinding occur. The adjustment of finished pulverized coal fineness is

Pulverizer - Wikipedia

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 coal is fine enough to be picked up by the air, it is carried through the classifier.
