The use of cyclone heat exchangers has énabled a reduction in both the rotary kiln length and the time required to achieve the temperature necessary to dry out the processed raw materials. Cement dust is introduced through the uppermost hot air duct and preheated within the various levels of the cyclone by means of hot combustion gas coming from the rotary kiln. In these cyclones, temperatures vary from 300°C (upper part) to 800°C (lower part).
