Burning and Grinding. After mixing the materials in appropriate proportions, the mixture is burned at a high temperature. Here the chemicals go through some reactions and are turned into calcium silicates which form the cement clinker. The cooled pellets are then ground in ball mills or tube mills and during this grinding process, a small proportion of gypsum is added.

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
