Coal mill, which is also known as coal grinding mill or coal milling machine, is used to pulverize and dry coal before it is blown into the power plant furnace in the coal-fired power plants. Coal mill is an important auxiliary equipment for coal-powder furnace, it has three methods to crush the coal lump and grind them into powder,it is crushing, impacting and grinding.

Coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is feed into the coal mill via a inlet pipe so that the roller coal mill such as ball mill or vertical mill can pulverize the coal into particles.

Air swept coal mill is the main equipment in cement plant for both drying and grinding of the powders. Compared with the ordinary ball mill, it has advantages of higher capacity, more convenient operation, safer usage, and more reliable performance.

The raw coal enters the mill via an airtight feed screw and is discharged onto the centre of the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track where the coal is ground between the table and the three rollers. The coal then continues over the dam ring and is entrained in the hot drying air that enters the mill house through the nozzle ring.

The air lifts the coarser particles back onto the grinding table and sweeps the finer particles up to the separator that lets the final product proceed to the mill outlet while returning the coarse fraction to the table for further grinding.Having left the mill at the top, the final product continues with the air to a cyclone or a bag filter where it is collected.
