Cement mill is also called cement ball mill, which is mainly used for grinding cement clinker in the cement production process. It is one of the important cement equipment. The output of cement mill is 21~155 t/h, and the specific surface area of cement is 3300~3800 cm ² /g.

The cement clinker is ground as finished cement, in a vertical roller mill for cement or in ball mills similar to those normally used for grinding hard raw materials in dry and semidry processes. However, the cement clinker is more difficult to grind than raw materials and must also be finer ground.

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
