  • Best energy consumption International Cement Review

    Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal millThe comminution efficiency of a HPGR is better than ball mills such that it consumes 30–50 % of the specific energy as compared to a ball mill Four circuit configurations of HPGR can be used in grinding of raw materials, clinker and slag such as : Pregrinding unit upstream of a ball mill Hybrid grinding Semifinish grindingEnergyEfficient Technologies in Cement Grinding | IntechOpen
