FL - HPGR - High pressure grinding roller

In 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.
