Primary air is admitted through the mill, which carries the finest coal particles to mill outlet. The air and coal mixture passes through a classifier, located at the upper part of the mill, where an additional particle separation takes place. Coarser particles return to the coal chute and fine particles are carried to the classifier outlet.

A classifier is one of the engine units in coal processing that serves to process coal to be ready to be used as fuel in the cement production. Coal that has been milled from the ball mill enters the classifier and separates coal material into fine and nonfine materials. Coarse

The BTM is a lowspeed mill that primarily grinds coal by impact and attrition. The VRM is a medium speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
