How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.

Coal feeds into a hammer mill, where it is simultaneously crushed and dried by the heat of the drying agent entering the mill. Next, coal is sent to the gasifier, where, in the presence of the oxidizing agents water vapor and air, which is waste air that was used as a drying agent from the mill, it is gasified to produce generator gas and slag.

Comminution is carried out to reduce the coal into smaller size. Depending on the various sizes involved, the coal is crushed and broken. Breaking is generally carried out on the largest coal size, crushing is used for mid ranges sizes and grinding is carried out for finest sizes. Grinding is done prior to utilization process.

Boilers. To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.

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.
