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.
