HRC TM High Pressure Grinding Roll (HPGR) has been acclaimed as one of the most energy efficient mining solution when used in the right application. The design is energy efficient due to the basic operating principle whereby the rotating rolls compress the feed and achieve breakage through inter particle compaction.
Our High Pressure Grinding Rolls (HPGR) can be utilised in a wide variety of minerals and size reduction duties, from coarse crushing for heap leaching through to iron ore pellet feed grinding. ... This results in superior equipment efficiency and reliability, providing a solid basis for circuit design and scaleup. The unique roll diameter ...

Peñasquito. a plant that processes sulphide ore using a high pressure grinding roll circuit and has an average gold recovery of 66%. Peñasquito is an important part of our overall plans to increase production by 20% by 2021. It's taking the following steps to increase production: investing 420 million to improve its processing facilities.
Ausenco designed a new comminution circuit for the existing concentrator to allow for the treatment of much harder ore. We created an innovative circuit incorporating High Pressure Grinding Rolls (HPGR) technology prior to the SemiAutogenous Grinding (SAG) mill to improve efficiency and increase throughput of the concentrator.
After the grinder is put into effect, the roller rotates around the main shaft, and rolls closely against the ring pressed by the high pressure spring and centrifugal force. (2) The blade carries materials to the space between the grinding roll and grinding ring, and materials are ground as the grinding roller rolls.
