The coal to be pulverized is delivered from a bunker 1 to a coal metering hopper 3 via a supply conduit 2. The metering hopper 3 is controlled, in the manner to be described below, so as to deliver measured quantities of coal to a roller mill 5 via conduit 4. The air which entrains the coal dust produced by mill 5 is provided by a blower 9.
It can be used for the grinding of coal, petcoke, clay, limestone, quicklime and many other materials no matter how different their grindability and abrasiveness may be or whatever fineness or drying degree is required.

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived …
In pulverized coal-fired (PCF) power plants (PPs), coal is pulverized in a mill, and it is then transferred to the burners and furnace volume for combustion. Depending on the physical and chemical properties of the coal, different types of pulverizing systems (e.g., vertical and horizontal air-swept ( Fig. 1 a and b )) can be used.
Coal Shop Safety. General Safety Rules Oxygen Concentration Coal grinding should be done in inert atmosphere Basic rules for the Oxygen during coal grinding are: < 14% O2 for Petcoke and Anthracite < 10% O2 for coal with volatiles below 30% < 9% O2 for coal with volatile above 30% The interlocked maxmax is 1 % point higher.

Originally Answered: What is a coal mill? To grind coal to fine powder for further firing at the huge huge burners fitted in the water walls of boilers in the coal fired thermal power plants mainly to heat water and convert to high pressure, high temperature steam, steam to be fed in turbines connected to electric generators to produce electricity.
The working principle of the coal mill is illustrated in Fig. 1.In normal practice, there are two coal feeders for each mill. Once the raw coal flows into the mill barrel with hot primary air, the iron balls inside the rotating barrel will continuously crash the coal until it is fine enough to be blown out the mill to the furnace.
