The mixture of different ingredients of cement, known as raw mix, is burnt in a rotary kiln at a temperature of about 1400–1500°C. This high temperature is required to form clinker, which consists of key compounds like tricalcium silicate (C₃S), dicalcium silicate (C₂S), tricalcium aluminate (C₃A), and tetracalcium aluminoferrite (C₄AF).
After burning, the clinker is cooled and then ground with gypsum to produce the final cement product.

The temperature at lower end in rotary kilns is between 1500 'C to 1650 'C is called clinkering zone, central portion of the kilns is between 700'C to 1200'C is called calcination zone and upper end is between 250'C is called evaporated zone. These centigrade are the standard burning in Rotary Kilns, (if dry or wet processing).

The temperature range in the cement kiln to burn cement klinker is maintained between 1300-1500°.

In dry process, a temperature is 1400 - 1500 * C.
In wet process, the temperature is 1500 - 1600* C.
In wet process, the temperature is 1500 - 1600* C.

It depends upon a type of requirement of cement and ingredient of cement 1000 to 1700.

Kiln temperature is 1300° to 1500° at material mixture fuses and mixes.

So as the material sinters and partially fuses to form nodular shaped CLINKER.
