In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. 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.

It was found that as a result of microwave treatment of lignite coals with 850 W for 12 min and 600 W for 23 min in microwave oven, inherent structural moisture may be removed completely from lignite coals. Grinding tests were carried out in stirred media mill for 5, 15, and 30 s of grinding period in order to determine the specific rate of ...
