High-Pressure Grinding - Maschinenfabrik Köppern2009. Redevelopment of the large mill line . High-pressure grinding roll presses (HPGRs) are emerging as an important comminution technology in the minerals processing industry. . Compared with conventional grinding, the HPGR process consumes significantly less energy, which in turn leads to a reduction in.high pressure grinding project mill site,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.
