CEMENT GRINDING OPTIMISATION
These models can be used to simulate cement grinding circuits and to assist their optimisation. The “work horse” of the cement grinding plant is the two-compartment ball mill, commonly called the tube mill. Significant advances in model development were achieved in recent years (Benzer et al, 2001, 2003) through research on industrial scale. The breakage and transport mechanisms are better

PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL
HOLTEC has undertaken Performance Optimisation of the cement grinding circuits by doing process diagnostic studies in many cement plants. The paper describes the approach for the process diagnostic study for the optimisation of a ball mill circuit and is supported with typical case study done by HOLTEC in a 1.5 mio t/a cement plant. The paper also describes the principle of the mill load

Sustainable cement production—present and future
01.07.2011· In open circuit ball mill grinding plants, slopes of about 0.8 to 0.9 can be achieved, and varying the PSD is possible only in relatively narrow ranges (e.g. by modification of grinding media composition). The required fineness of cement can only be adjusted by the selected fresh material feed. In the case of high pressure comminution with vertical roller mills (VRM) or high-pressure grinding
