high high pressure roller iron ore grinding

(HPGR) high pressure grinding rolls/rollers for cement ...

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid []

High Pressure Grinding Rolls in the mining ... - AT Minerals

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.

Why HPGRs are revolutionising mill circuits

Aug 07, 2019  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.
