How Cement Is Made

Clinker comes out of the kiln as grey balls, about the size of marbles. Clinker is discharged red-hot from the lower end of the kiln and generally is brought down to handling temperature in various types of coolers. The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency. ...

Clinker: combinability of mixes - Understanding Cement

Importance of the liquid phase. During clinkering, the clinker contains solid phases and a liquid phase. The bulk of the clinker remains as a solid. At the highest temperatures reached by the clinker, perhaps only about 25% of the clinker is a liquid and the solid phases are then mainly alite, belite and free lime.
