kiln requires additional length (in comparison to a dry kiln). Additionally, to evaporate the water contained in the slurry, a wet kiln consumes nearly 33 percent more kiln energy when compared to a dry kiln. Wet-process kilns tend to be older operations as compared to dry-processes where raw materials are fed into the process as a dry powder.

Jan 01, 2011· 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.
