Cement clinker Wikipedia

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.

Cement Grinding Satarem.co

The clinker grinding process is the stage where the particles are reduced in size,a combination of impact and abrasion and their efficiency depends on the controls realized on the size of the product, this stage of cement production is the stage with the highest energy consumption of the full process, in addition to being directly related to the properties and final quality of the product.

Cement mill Wikipedia

The hardness of clinker is important for the energy cost of the grinding process. It depends both on the clinker's mineral composition and its thermal history. The easiest-ground clinker mineral is alite,so high-alite clinkers reduce grinding costs, although they are more expensive to make in the kiln.
