that distinguish the two basic bearing categories – ball bearings and roller bearings. There is a groove called the ball path on both the inner and outer races of ball bearings in which the balls roll. For roller bearings, the rollers roll on the flat surface of each race. This surface is called the roller path.

The finely ground material discharges along the outer periphery of the ball races. For the pulverization of coal, hot air, introduced between the lower race and the pulverizer housing, lifts or carries the fines to a cyclone classifier at the center of the pulverizer.
A particularly common kind of rolling-element bearing is the ball bearing. The bearing has inner and outer races between which balls roll. Each race features a groove usually shaped so the ball fits slightly loose. Thus, in principle, the ball contacts each race across a very narrow area.
