「How HPGRs compare to conventional milling」

Within this highlycompressed bed of rock, an Enduron® HPGR delivers as much as 5N/mm in pressure, significantly reducing even highlycompetent ores, such as diamond, gold, copper and coarse iron ore, while achieving throughputs of up 9,000 t/h that ball mills cant match.

「HPGR High Pressure Grinding Rolls」

HPGR test results published by Grier (1992) on gold ores from the Mt. Todd project showed significant energy savings for a HPGR/Ball Mill circuit as compared to a SAG/Ball Mill plant. By adding a Polycom highpressure grinding roll, the throughput of existing plants can be increased by as much as 150% while simultaneously reducing the power consumption by up to 20%.

「Will HPGR replace SAG Mill and Vertimill displace Ball」

To place a ball mill or a VERTIMILL directly on the HPGR product may work on soft iron ores but will not work well on harder ores that require over about 7 kWh/t to achieve a T80 of 1.7 mm. When hard minus 10 mm scats are present (referring to HPGR product), the ball mill efficiency is reduced. Note that the hardness of these scats is not
