Silicate cement production technology in cement production representative, is composed of limestone and clay as raw material, crushing, ingredients, raw material made of finely ground, then calcined mature cement kiln feed material, and then cooked add appropriate amount of gypsum materials (sometimes mixed with mixed materials or additives) made of finely ground.

Cement production with different raw material preparation, can be divided into dry (including the semi-dry) and wet (including the semi-wet method) of two.
① Dry production. The raw material drying and grinding the same time, or to drying by grinding into a powder raw material after the dry kiln feed material calcined mature way. But there are also adding an appropriate amount of raw material powder made from raw water ball into Lepol mature material calcined kiln method, called semi-dry, still produced a kind of dry.

② wet production. Health Canada Gouache grind the raw material slurry, the feed material wet kiln burning mature way. There will be wet method after dewatering of raw slurry, made of blocks of raw materials into the kiln burning mature approach, called semi-wet method, a kind of production is still wet. Production of the main advantages of dry heat loss is low (such as with a dry preheater kiln heat consumption of clinker for the 3140 ~ 3768 kJ / kg), disadvantage is not easy even raw ingredients, shop dust large, high power consumption . Wet production is simple, easy to control raw material composition, product quality, slurry transportation convenience, shop dust and less advantages, disadvantages is the high heat consumption (heat consumption of clinker is usually 5234 ~ 6490 kJ / kg).
