28/07/2020 Highpressure grinding rolls were first applied in the minerals industry in 1985 in cement plants The main objective for the use of HPGR was the significant energy savings achievable Today, they are also being used by diamond mines and for the communition of coal as well as for the grinding of slag, iron and chromium concentrates (Figure 4)13/07/2016 Primary grinding in the highpressure grinding roll increases the capacity of an existing dry ball mill operation Even greater increases in capacity can be achieved if the Polycom is operated in hybrid mode Hybrid grinding means that a part of the separator tailings (which are recirculated to the ball mill) is diverted and fed to the Polycom together with the fresh feed HPGR High Pressure Grinding RollsHigh pressure grinding rolls (HPGR) are used for size reduction or rocks and ores They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain sizeHigh pressure grinding rolls (HPGR) Outotec
