Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
To support the production of cement, the plant has modern vertical roller grinding mills along with tube mills both for raw meal as well as coal. Cement grinding is achieved exclusively by tube mills/horizontal ball mills. The final products of the plant include PPC, OPC, PSG and other special cements.
