In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thickness of the material bed between roller and table is a multiple of the particle size.

BASIC CEMENT PLANT LAYOUT The Cement Institute

This grinding is done using either ball mills or vertical roller mills (VRM). The raw material is simultaneously dried. Ball mills use impact with attrition principles for grinding the raw material. Inside the ball mills, various sizes of balls are used and classifying liners are used to maintain the position of different sizes of balls.

Grinding of Calcined Clays and Its Effects on Cement Properties

The particle size distributions of clinker and calcined clay were almost identical after intergrinding. Significant savings in specific energy consumption of up to % were found in relation to grinding, with a negligible reduction of strength development of, on average, % compared to separatedgrinding samples. 4 Conclusion
