Most cement plants have restrictions with regards to their finish cement temperature, which should in a lot of cases not exceed 160 F (71 DEG C). Since in most cases the feed temperature of clinker is higher than 220 F (104 DEG C) and a ball mill creates additional heat, because of its inefficiency, additional cooling is required.
The kiln in cement plant can be divided into cement rotary kiln and vertical shaft kiln. They are both the commonly used cement kiln in the cement production line. AGICO offers quality cement equipment, like cement kiln, cement crusher, etc.

Cement is manufactured by heating a mixture of ground limestone and other minerals containing silica, alumina, and iron up to around 1450 C in a rotary kiln. At this temperature, the oxides of these minerals chemically transform into calcium silicate, calcium aluminate, and calcium …
Finish Milling. When it comes to mills used in the final phase of cement manufacturing, equipment like rotary airlocks function similarly to when used with raw materials, minimizing the amount of false air coming into the mill. Though rotary airlocks do the same job, they must deal with more demanding conditions when acting as finish mill feeders.

After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.
