Why HPGRs are revolutionising mill circuits |
The high pressure of HPGR's "bed-breakage" creates micro-cracks in the ore, promoting improved mineral recovery at coarser size fractions. This means less leaching acid is required and percolation periods are shortened, reducing costs and maximising recovery in less time. In the diamond industry, the HPGR acts as a selective grinder ...

How HPGRs compare to conventional milling |
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 flexible when it comes to meeting your campaign timings. When tyres do wear down and need to be replaced, the Enduron® HPGR's ...
