Iron Ore Final Grinding by High Pressure Grinding Rolls
Description. 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 closed-circuit grinding in preparation of ball mill feed right down to the other end of the particle size spectrum for iron ore pellet feed preparation.
