Cement Kilns: Clinker
Portland cement clinker is the essential ingredient of Portland cement. Portland cement is obtained by grinding clinker with only minor amounts of a few other minerals, so its composition does not depart far from that of clinker. Other cements (i.e. non-Portland cements, for example pozzolanic cements, blast furnace slag cements, limestone ...

Le clinker est un constituant du ciment, qui résulte de la cuisson d'un mélange composé d'environ 80 % de calcaire (qui apporte le calcium) et de 20 % d'aluminosilicates (notamment des argiles qui apportent le silicium, l'aluminium et le fer). La « farine » ou le « cru » est formée du mélange de poudre de calcaire et d'argile. Cette cuisson, la clinkérisation, se fait à une ...

It is difficult to calcine clinker because of the complex chemical composition of these raw materials and the existence of many harmful trace components. When the surface area of the clinker is (350±10)m²/kg, the grinding time gradually increases to 38min, and the maximum grinding time reaches 40min(32min in normal condition).

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.
