 · In a coal based power plant coal is transported from coal mines to the power plant by railway in wagons or in a merry-go-round system. Coal is unloaded from the wagons to a moving underground conveyor belt. This coal from the mines is of no unifor... Crushed coal from the raw coal bunker is fed by gravity to a dryer where hot air is passed through the coal to dry it. The dryer may use waste flue gasses, preheated air or bleeder steam as drying agent. The dry coal is then transferred to the pulverising mill. The pulverised coal obtained is transferred to the pulverised coal bunker (bin).

 · 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. The crushed coal is fed to the drier from the raw coal bunker by gravity. The drying of coal is effected either by using hot gases, preheated air or bled steam. The dried coal is fed to the pulverizer with the help of feeder. The pulverized coal is carried from the pulverizer mill with the help of air and it is separated in the cyclone separator.
