High pressure roll grinding is normally used as super fine crushing process,which can be as the third or fourth stage of a crushing process, also can be used in the semi-autogenous grinding process for hard rocks. The input material size for HPGR normally is 20~60 mm,and output size can be less than 3mm.
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.
High pressure grinding rolls, also called roller presses, have been used in the treatment of iron ore, copper (Fig.), gold, diamond and various other ore types for many years. Contrary to conventional crushing rolls, the particles are broken by compression in a packed particle bed, and not by direct nipping of the particles between the two rolls.
