Energy efficiency measures for clinker production. It is found the largest amounts of thermal energy saving, electrical energy saving, emission reductions are 4.1 Giga Joule per ton, 35 kilo Watt

History of cement

Rotary kilns heat the clinker mainly by radiative heat transfer and this is more efficient at higher temperatures, enabling higher burning temperatures to be achieved. Also, because the clinker is constantly moving within the kiln, a fairly uniform clinkering temperature is achieved in the hottest part of the kiln

2021-6-11  The makeup of a kiln. During the operation of the rotary kiln, flames can reach temperatures as high as 1900°C (3452°F) in order to heat raw materials to roughly 1500°C (2732°F). As a result, these materials become partially molten and undergo a series of physical and chemical reactions to become the primary constituent of cement.

Utilization of cement kiln dust (CKD) in cement mortar

2006-10-1  Cement kiln dust, on the other hand, gets rid of extra step, as the initial mixing and compacting is enough to stabilize the material sufficiently (Miller and Zaman, 2000). Cement is often used for soil stabilization in transportation construction. Cement kiln dust is an effective alternative to cement, which is more expensive than finer CKD.
