Energy and exergy analyses of a raw mill in a cement production
The objective of this study is to perform energy and exergy analysis of a raw mill (RM) and raw materials preparation unit in a cement plant in Turkey using the actual operational data. The RM has a capacity of 82.9 ton-material hourly. Both energy and exergy efficiencies of the RM are investigated for the plant performance analysis andFurthermore, the mercury enrichment and effects of dust treatment were evaluated based on the field tests conducted in two Chinese cement plants. The mercury cycling between the kiln system and the raw mill system was the most important aspect and contributed 57–73% to the total amount of mercury emitted from the kiln system.Analysis of material flow and consumption in cement

Cement Grinding Plant Overview Cement Grinding Unit AGICO Cement
As we all know, the cement production can generally be divided into three processes: raw material preparation, clinker production and finished cement production. The cement grinding plant is a vital link of the finished cement production. The cement grinding plant also called cement grinding unit, is used to grind clinker into qualified cement.Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment in grindingOperational parameters affecting the vertical roller mill

Digitization and the future of the cement plant McKinsey
When envisioning the cement plant of the future, it is important to understand the reference for a typical plant today. Our reference plant is a five-stage preheater-calciner kiln with a vertical raw mill and two cement ball mills. It has an annual production capacity of one million metric tons of cement and produces several types of β [1 − α; p 2; n − p − 1 2] = (1–α) th quantile of β [p 2; n − p − 1 2] distribution.
