Cement Rotary Kiln & Vertical Shaft Kiln

Cement rotary kiln can be divided into the dry method rotary kiln and wet method rotary kiln. Their main difference is that the former calcines dry powder raw meals, while the latter calcines slurry raw meals. Therefore, the wet method rotary kiln needs to evaporate additional material moisture, about 30% to 40%, which consumes more heat and ...

Model predictive control of a rotary cement kiln

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.
