production process of cement raw materials

Raw Mill, Cement Raw Mill, Raw Mill In Cement Plant

Raw mill is generally called cement raw mill, raw mill in cement plant, it refers to a common type of cement equipment in the cement plant.In the cement manufacturing process, raw mill in cement plant grind cement raw materials into the raw mix, and the raw mix is sent to the cement kiln to make cement clinker, next, clinker and other admixtures will be ground into finished cement by cement mill.

The Cement Industry

The cement manufacturing process requires the use of raw materials such as limestone and additives to control the alumina, silica and iron content. In addition, a relatively high amount of energy is needed to convert the limestone to calcium-oxide and to solidify and compress the material at 1,450C.
