Clinker Production - an overview | ScienceDirect Topics
The hot gases from the preheater tower can be used as a heat source to dry the raw meal for clinker production. In the cement production process, elements such as chlorine and sulfur are released. These elements bind to the fired raw material at a temperature of 1200 °C -1300 °C, and then evaporate depending on the degree of volatility.

From there the raw material, now called kiln feed, is fed to the top of the kiln for sintering. Raw materials are cooked and turned in a kiln at approx. 1,450°C. By chemical conversion, a process known as sintering, a new product is formed called clinker. Clinker is a combination of all the raw materials baked in the kiln.
