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 high-pressure 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%.

High pressure grinding rolls (HPGR) liming

High 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 stone size.

How HPGR compares to conventional milling The Weir

HPGR wear vs conventional mills. Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis. This makes HPGRs more

High Pressure Grinding Rolls (HPGR) TENOVA

The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the leaching liquid. Also, flotation efficiency is further enhanced through the use of HPGR comminution.

HPGR High Pressure Grinding Rolls Weir

Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid volume, exceeding its compressive strength with equal pressure being applied to
