Sustainable cement production—present and future

 · In addition to the ball mill, high-pressure grinding systems such as vertical roller mills (VRM) or high-pressure grinding rolls (HPGR) are in use today for cement grinding. The specific energy demand of these grinding systems is comparatively low, but the cement from high-pressure mills shows slightly different properties in terms of its particle size distribution (PSD).

Effect of pre-crushing with a ­vertical shaft impactor (VSI) …

High pressure grinding roller (HPGR) crushers are used conventionally as a pre-crusher ahead of the ball mill to reduce the specific energy consumption of the grinding stage or to increase the grinding capacity of the circuit in cement grinding circuits [3, 4, 5].
