High Pressure Grinding Roll for advanced crushing |FLSmidth
The HPGR exposes feed material to very high pressure for a short amount of time. The compression typically causes the rock to crack and cleave along the grain boundaries, weakening the rock structure and exposing the ore particles. This high pressure also creates a large amount of fines and causes the formation of microcracks in the larger particles, lowering the Bond work index of the ore and reducing the ball millYGM High Pressure Grinding Mill-Vanguard Machinery,Inside the host of the high-pressure grinder, a 1000-1500 kg high pressure spring is fastened on the roller hanger.
