cement manufacturing
Cementmanufacturingis a two-stage process. Materials such as limestone that contain calcium oxide are mixed with silica and alumina materials such as sand, shale or clay. The raw materials are usually dried and ground, and then the mixture is heated in a rotary kiln to form clinker. The clinker is then mixed with gypsum and other materials

Cement Kilns: Dry and semi-dry process kilns
The modern rotary kiln is solely used for the sintering stage, for which it is uniquely well adapted. The initial reluctance to employ dry process in Britain was associated with the industry’s concentration in the chalk areas, where processes other than wet must always be questionable.

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.
