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. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Cement clinker

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.

Clinker: combinability of mixes Understanding Cement

This is because at an AR of about 1.4, there is more clinker liquid at a lower temperature and combinability is optimised. (Minor constituents such as MgO can alter this optimum AR). The intrinsic reactivity of the raw materials some types of silica, for example, will react more easily than will others.
