Iron Ore Final Grinding by High Pressure Grinding Rolls . High pressure grinding rolls (HPGR) technology is growing to be a common comminution tool in iron ore processing The technology finds a wide acceptance and presents specific benefits in coarse ore grinding and closedcircuit grinding in preparation of ball mill feed, right down to the other end of the particle size spectrum for iron ore.
The comminution circuit at Vizcachitas, where the HPGR circuit will be incorporated, is a three stage crushing circuit using a gyratory primary crusher, three cone crushers in open circuit and two HPGR as a tertiary stage arranged in a closed circuit followed by ball mills.
HPGR is an energy efficient crushing equipment used to reduce 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 volume, exceeding its compressive strength with equal pressure.
