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.
Highlights We analyzed a raw mill and investigated the first law and second law efficiency values. Performance assessment of a raw mill indicates that the grinding process involves energy and exergy losses. The ambient air conditions affect efficiency and production capacity of the mill. The specific energy consumption for farine production is determined.
