coal mill in cement manufacturing process

Cement Manufacturing

Mills belong to a class of equipments that accomplish comminution of materials in the fine range. There are two types of mills which are mostly used in cement plants for grinding raw mix viz. Ball mills and VRM. Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84% passing 90 microns.

Manufacturing Process Of Cement

Pyro Processing and Clinkerization. The fuel is ignited and burned out in the combustion zone. The sintering process and the formation of clinker occur inside the kiln. Hot clinker is cooled in the cooler. Ambient air is used to cool the clinker and partially used for coal combustion. The cooled clinker is stored in the clinker yard/clinker silo for cement grinding.
