HRC™ high pressure grinding rolls (HPGR) - High pressure grinding rolls are an energy efficient grinding solution, and now has improved this technology even further. The HRC™, our innovative approach to HPGR technology, is like no other HPGR on the market. Main features of the HRC™ HPGR are: Patented anti-skewing Arch-frame; Tungsten.FL - HPGR - High pressure grinding rollerIn high-pressure grinding roller comminution the feed material is exposed to very high pressure for a short time. The high pressure causes the formation of microcracks in the feed particles and generates a substantial amount of fine material. The pressed material can be fed directly to a given size ball mill, making it possible.
