HPGR is an energy-efficient size-reduction comminution device used in mineral processing industries since the mid-1980s because of its unique ability in energy reduction ; improved gangue-mineral value liberation ; induction of micro-cracks at the grain-boundaries, which ultimately results in higher grade; and recovery of mineral values in the ...

High-pressure grinding on a whole new level

M ajor design breakthroughs by Minerals in high pressure grinding roll (HPGR) technology at Freeport-McMoRan Inc's (FCX) Morenci open-pit mine in Arizona have resulted not only in the world's largest HPGR in operation – the HRC 3000 – but also in significant progress overcoming some of the technology's greatest challenges. The HRC …

High pressure grinding rolls (HPGR)

HRC™ Series high pressure grinding rolls (HPGR) are most often utilized when the processed material is hard rock. However, they can also refine softer materials like industrial minerals. The smaller models of the HPGR are particularly productive in producing manufactured sand for asphalt and concrete production.

Plant and Machinery

High-pressure grinding rollers (HPGR) During the high-pressure comminution process, rather than being crushed between the roller surfaces, individual grains or particles are in effect compacted to a dense flake through exposure to relatively high pressures. After de-agglomeration, the flake normally shows a substatial amount of completed or incipient …

Why gold mines are adopting HPGRs to increase production …

How HPGR improves gold recovery. There are two main ways mines recover gold ore from the gangue, and HPGRs can assist with each process. One of them is heap leaching and for mines using this process, we've found that the most efficient setup is to have a HPGR perform tertiary grinding immediately prior to recovery, completely avoiding the use of a …

Outotec on HPGR's leading edge

Are there any enhancements to HPGR technology you expect to affect productivity (and power efficiency) in the next few years? A major limitation of the efficiency of HPGRs is the reduced press force profile near the edge of the rolls, which can cause product to be nearly the size of the feed material. This is commonly referred to as the "edge ...

How HPGRs compare to conventional milling |

Within comminution circuits, High Pressure Grinding Rolls (HPGR) are increasingly replacing conventional SAG, rod and ball mills for hard rock reduction – owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. Not only do they require as much as 40% less energy than traditional …
