Cement Kilns: Clinker Thermochemistry

The value of H is in kJ/kg. The oxide percentages are those in the loss-free clinker, normalised to 100.00%. If not all oxide values are available, then the calculation can be performed on the reduced set, again normalised, but bear in mind that in a typical clinker, the contributions of Ti, P and Mn lower the value by about 15 kJ/kg.

Composition of cement - engr.psu.edu

The materials are then fed through a kiln at 2,600º F to produce grayish-black pellets known as clinker. The alumina and iron act as fluxing agents which lower the melting point of silica from 3,000 to 2600º F. After this stage, the clinker is cooled, pulverized and gypsum added to regulate setting time.
