Why HPGRs are revolutionising mill circuits | Weir
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.
