iii Abstract Vertical Roller Mill (VRM) technology was developed more than four decades ago and has found applications mostly in cement grinding operations and in power plants for coal grinding.
Ball And Race Mills In this mill the coal passes between the rotating elements again and again until it has been pulverized to desired degree of fineness. The coal is crushed between two moving surfaces, namely, balls and races. The upper stationary race and lower rotating race driven by a worm and gear hold the balls between them.
