Example Of High Pressure Roll Grinding EquipmentJoyal

High-pressure grinding roll was considered to have great potential in improving capacity and reducing energy consumption in a grinding circuit [45]. Comminution in the high-pressure grinding roll is the result of the high interparticle stresses generated when a bed of solids is compressed as it moves down the gap between two pressurized rolls. Such high interparticle stresses result in a much
