Mill Speed an overview | ScienceDirect Topics

In the ball-and-race mill (Fig. 13.3), balls are held between two races, much like a large ball bearing.The top race or grinding ring remains stationary while the bottom race rotates. As the coal is ground between large diameter balls and the ring, the balls are free to rotate on all axes and therefore remain spherical.
