HPGRs Grind Out Larger Role in Plant Productivity | E & MJ
Fortuna Silver Mines, which recently began commissioning and ramp-up at its $320 million Lindero gold project in Argentina, included HPGRs in its tertiary ore crushing circuit, based on testwork that indicated HPGR-processed ore would provide higher extraction rates than that obtained using conventional cone crushers or a vertical shaft impactor (VSI).
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 …
HPGRs for Low to High Tonnage Applications
Why HPGR? The energy-efficiency of crushing and grinding is an increasingly important issue across all processing industries requiring comminution or size reduction of material. Today, high energy costs coupled with the worldwide initiative to reduce CO2 emissions have made state-of-the art HPGRs indispensable in many processing industries.

Kışladağ and Minerals on the HPGR-backed gold recovery trail
The story that led to the installation of a Minerals Enduron® high pressure grinding roll (HPGR) at Eldorado Gold's Kışladağ heap leach operation in Turkey is a fascinating read, as well as a great example of the benefits of using such technology.
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 …
polycom® HPGR
In the cement industry, high-pressure grinding rolls have proven their worth - not least due to their low energy requirements - and have been used worldwide for decades for grinding cement raw material, cement clinker, and granulated blastfurnace slag.
