Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400C-1500C in the rotary kiln.

In the rotary kiln, the carbonate is further rapidly precalcined and a series of solid phase reactions occur to form minerals in the cement clinker. As the temperature of the material increases, the mineral becomes a liquid phase and reacts to form a large amount (clinker). After the clinker is fired, the temperature begins to decrease.
