Sustainable cement production—present and future

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 rolls (HPGR), the
