An Introduction to Clinker Grinding and Cement Storage

Clinker Grinding. 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 semi-dry processes. However, the cement clinker is more difficult to grind than raw materials and must also be finer ground.

Cement clinker - Wikipedia

The second raw material (materials in the rawmix other than limestone) depend on the purity of the limestone. Some of the second raw materials used are: clay, shale, sand, iron ore, bauxite, fly ash and slag. Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln at high temperature.
