In the cement kiln, all the ingredients are heated to about 1400–1500 °C in huge horizontal cylindrical steel tubular vessel called rotary kiln, lined inside with special Refractory material. Kilns are as much as 3–7 m in diameter and about 60–75 m in length.
Cement production is a highly energy-intensive process, and the rotary kiln is the most important part of the process. Having a comprehensive model of the kiln in order to reduce manufacturing costs, better performance can be created. In this paper, the influence processes in a simulated cement rotary kiln and operating parameters on the …

Preheater kiln for the cement clinker production with four cyclone stages in the preheater tower, the rotary kiln and the cooler. Usually, at this stage in modern kilns a precalciner is introduced. Essentially, a precalciner is an additional combustion chamber, which is able to drive the dominant endothermic process of calcination.
