High Pressure Grinding Rolls (HPGR) | TAKRAF
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 ...

How does air classification work with Enduron ® HPGR? To maximise size reduction, HPGRs traditionally operate in closed circuits utilising a wet or dry screen to classify or separate the higher proportion of fines generated by the rolls. In competing high power size reduction technologies like SAG, ball, and rod mills operations use water and ...

that the adoption of HPGR brings even bigger energy savings per tonne of ore processed. As a result, most greenfield projects processing hard (competent) rock include HPGR as part of their standard comminution flow sheet. Downstream capacity uplifts of up to 40% make Enduron® HPGR a great solution for brownfield optimisation.

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 ...

High Pressure Grinding Roll for advanced crushing |FL
Our HPGR is a perfect complementary tool to work in conjunction with, and even enhance the performance of traditional grinding mills and fixed-gap crushers. 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 ...
