Coal Mill in Cement Plant 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.

Most explosions in coal mill plants have their initial ignition location within the mill chamber. This is because the mill chamber is the section of the plant in which the conditions for the ignition of air dispersed fuel are most favourable, as well as the risk that tramp metal gets trapped in the grinding media. Also, grinding causes impact ...

One of the key subsystems in thermal power plants is the coal mill used to pulverize the coal before it gets into the plant furnace. The interior of the mill rotates and the plates located on the inside grind the coal into a small size powder. During that process the plates within the mill slowly get depleted and the productivity of the mill ...
