The diameter of roller was 250 mm and the length was 120 mm. By operating the hydraulic transmission system, the roller pressure was kept constant at 25.2 kN, 31.5 kN and 37.8 kN respectively. Correspondingly, the pressure intensity on the cross section of the roller could reach 0.8 Mpa, 1.0 Mpa and 1.2Mpa respectively.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

High Pressure Grinding Rolls (HPGR) circuits have the potential to reduce the Mining Industry's CO 2 emissions by up to 34.5 megatonnes/year, or 43.5% when compared to the established Autogenous (AG)/Semi-Autogenous (SAG)/Ball mill circuit alternatives. However, uptake of HPGR technology has been relatively slow.

High Pressure Grinding Rolls are generally thought to only be effective in controlled "dry" grinding applications, however (depending on the material saturation level) they can readily process minerals well above 10% moisture. This gives HPGR's the flexibility to fit into a wide array of applications with both wet and dry classification.
