Raw Mill for Cement Plant
Raw mill is also called raw material mill, which is the essential equipment in the production process of cement. It has large application such as raw mill in cement plant, building materials, metallurgy, electric power and chemical industry, which is mainly used for the grinding as well as drying of cement raw materials and other materials.

25.08.2020There are three steps of the high-temperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.

Cement Kilns: Size Reduction and Grinding
Rawmill systems typically require a feed of maximum size 5-10 cm, so a crushing stage is first required. In the kiln, the finely-divided rawmix is sintered, resulting in production of hard clinker of typical size 1-50 mm. In order to produce cement, this has to be ground, again to a powder of maximum size about 100 μm.
