The air picks up the coal dust as it flow between the ball and races and then it enter into the rotating classifier above. The oversized particles are thrown out due to cyclonic action of air and coal particles to the wall of the classifier and only fine coal dust of required size is discharged from the top of classifier and supplied to the burners.

The BTM is a low-speed 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
