Cement varied greatly from mill to mill according to the mineral content of the limestone. Different limestone layers could even produce vastly different cement from the same quarry. Shepherdstown’s cement in particular was highly regarded. Compared with other products in the same industry, the output increases by 15-20%, power consumption reduces by 10%. Moreover, the temperature of finished product can reduce by 10-20℃. Cement mill is mainly used for final product grinding 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 ambient air is heated up to 290°C. After that, a small amount of this air is employed as an additional oxygen source in the kiln and a bigger part is supplied for cement mill heating if it is under operation. The operation mode with disabled cement mill envisages air cooling down before the filter bags.
