Coal Mills are used to pulverize and dry to coal before it is blown into the power plant furnace.. Operation. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.

Based on the Unit load demand pulverised coal moves from the Intermediate Bunker to the Furnace. A suction fan helps in sucking the pulverized fuel to the furnace. This system is suitable, where the boiler load varies and the mills consume huge power. But, the disadvantage is that the capital cost is high due to extra bunkers and fans.

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.
