Coal mill is also called coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are air-swept ball mill and vertical roller mill.. At present, most cement plants use coal as the main fuel in the clinker production process.

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

The Cement/Lime industry has had to search for a way to reduce costs and this has resulted in the near standardization of coal-fired (or coke) systems for firing up the kiln. These systems are indirect-fired, where coal is crushed in mills/pulverizers, then classified by size for collection as a fuel or dust through a heated air conveyance network.
