In the cement manufacturing process, limestone, sand, shale, clay, and iron ore are used as main raw materials. The whole cement process in clued four stage: raw material crushing, calcination, cement grinding, packaging and distribution.

Raw material are complete preheating and precalcining in the cyclone preheater, next procedure is into the rotary kiln in the firing of clinker. In rotary kiln, carbonate further quickly decomposes and start a series of solid reaction, then form the important material in cement clinker. As the material temperature close, mineral will become liquid, dissolved in the liquid phase reactions and form a (clinker). Clinker firing, temperature began to drop. Finally, cement clinker cooling machine will cool the rotary kiln of high temperature clinker to a temperature which downstream conveying, storage tanks and cement machine could bear. At the same time, recovery afterheat of the high temperature clinker, so as to improve the system of the thermal efficiency and quality of materials.

After calcination, the cement clinker need to regrind to final cement products. Fineness of the final products, amount of gypsum added, and the amount of process additions added are all varied to develop a desired performance in each of the final cement products.
