    Grinding of mineral mixtures in high-pressure grinding rolls

    Sep 01, 2009· The escalation of energy costs and the effort to reduce steel consumption has accelerated interest towards installing high-pressure grinding rolls (HPGR) in mineral processing plants. First of all, because an ore is an admixture of two or more minerals that differ in their chemical and physical properties, variations in the ore being comminuted can have significant effects.
