    The mixture of raw materials is fed from the upper end of the kiln. The raw mix moves downwards due to the inclination and rotation of the kiln. Once the clinker passes the flame, it enters a short cooling zone and drops off in temperature. The clinker leaves the kiln at about 1000°C and falls into a cooler.

    Alite formation Alite forms by the transition of some of the belite to alite and also directly from free lime and silica to alite. This occurs rapidly once the clinker temperature is above about 1400 °C. Evaporation of volatiles Volatile phases in the cement kiln are principally alkali sulfates, with a much smaller proportion of alkali chlorides. As the part-burned feed approaches the burning zone, these volatile phases are in .
