Ball and Race Mill ~ ME Mechanical

Jul 07, 2017  In ball and race mill the coal passes between the rotating elements again and again until it is pulverized to the desired degree of fineness. The coal is crushed between two moving surfaces namely balls and races. A worm and gear drove the upper stationary race, and the lower rotating race holds the balls between them.

Race (bearing) - Wikipedia

The deformed ball and race do not roll entirely smoothly because different parts of the ball are moving at different speeds as it rolls. Thus, there are opposing forces and sliding motions at each ball/race contact. Overall, these cause bearing drag. "V" groove raceways distribute the load evenly over the balls as they travel on four points of ...
