A generic schematic of a self-inert coal milling and drying system from mill supplier Loesche. Too low drying capacity was a problem especially when the hot gas generators were operated on syngas, but also on natural gas, as the capacity was sometimes insufficient. There were several reasons for this.

The MPS coal grinding mill with a high drying capacity is very suitable for grinding lignites with feed moistures of as much as 45 per cent. Depending on this high feed moisture, the mill rating is determined by drying whereas for anthracite, hard coal and petcoke the rating of the mill is determined by grinding. The great
Every coal pulverizer is designed with a particular fuel grinding capacity or throughput at a certain Hardgrove grindability index (HGI), based on a defined raw coal size, moisture content, and ...
Additionally, with less fuel moisture, more complete drying of coal can be achieved in the mill. This results in increased mill exit temperature (the temperature of the coal and primary air mixture at mill exit), better conveying of coal in the coal pipes and less coal .
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.
The maximum possible grinding capacity depends on the coal character (grain composition, grindability index, rock concentration, moisture content etc.), on the dust system characteristics (drying, ventilation and grindability) and on the amount of coal fed into the mill, on the coal feeding system and
Air swept coal mill is an ideal coal processing equipment that can both grind and dry, with characteristics of high efficiency, energy saving, environmental protection, 8% and above of its grinding coal can pass through the 200 mesh screen, and the water content can be under 2%, it is an ideal grinding equipment for coal powders that are used in industrial furnaces and rotary kilns and other ...
Cold Air Locking at Mill Inlet: This is very important for coal mill, as ambient air throttling the drying capacity of mill as well as increases the oxygen content of kiln gases making it riskier. Oxygen percentage of more than 12-14% is considered catalyst for fire/explosion risk.
Features of Coal Grinding Mill. Air-Swept Coal mill is with rim drive, motor drives the grinding mill to rotate through reducer and gears. Grinding storehouse adopts modular layout so that coal mill has greater adaptability to the moisture of raw coal, improving the mill's grinding capacity.

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. Coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler.
The design "capacity" of the same pulverizer will grind 135,000 pounds per hour with fuel that is 55 HGI (Hardgrove Grindability Index) coal, ¾" raw coal top size, 7% moisture and produces pulverized coal that is 70% passing 200 mesh fineness (red line). This is pretty standard.
