Ball Mills: A ball mill is a cylindrical machine with a horizontal axis, some of which contain grinding media such as steel balls or steel rods. The mill receives coal feed and grinds it by the impact and friction of rolling balls. For grinding coal, ball mills are frequently used in cement factories and coalfired power plants.

The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a predetermined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.

In the ballandrace mill (Fig. ), balls are held between two races, much like a large ball 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.
Roll crushers are often used in coal processing plants to reduce the size of coal before it is transported. Ball Mills: Ball mills are a common choice for grinding coal. They work by rotating a ...
Mills A ball or roller between two races or rings provides the grinding surfaces on which pulverization occurs. One or both of the races may rotate against a ball or roll (in a RingRoll Mill, the rolls may rotate while the ring is stationary).
