The HPGR also ties in well with 's MissionZero sustainability strategy. "The growing focus on sustainability is driving new interest in the High Pressure Grinding Roll (HPGR). Using a HPGR as part of a 100% dry comminution circuit will help mines reduce or eliminate water usage where this is possible.

IMS Engineering's involvement in the comminution industry started in 1962 when we became the licensees of HAZEMAG's range of horizontal shaft impactors, hammer mills, and roll crushers in Southern deal also included MinPro's feeder breakers, horizontal jaw crushers and related equipment. In the late 80s, IMS Engineering developed their comminution service and entered into a ...

For the HPGR tests, the moisture was adjusted and the sample was homogenized using a rotatory splitter. Three HPGR tests were conducted at a roll speed of m/s, moisture content of % and pressing forces of 3, 4, and 5 N/mm 2. The PPT sample was crushed to − mm using a cone crusher and the moisture content was adjusted to %.

HPGR Testing. Determination of energy requirements for HPGR are typically done using a pilot-scale HPGR (for instance LABWAL), though for metallurgical scoping studies or variability programmes where sample masses are limited, static compression tests can also be done using a piston-die setup. GSL has two piston-die combinations available which ...

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 ...

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 ...

The results showed that the HPGR-ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG-ball mill circuit at the same P80 grind size of 160 mircons (μm). At a grind of 80% passing 75 μm, the HPGR-stirred mill circuit showed a 34% reduction in energy compared to the base case.

HPGR technology works by exposing the feed material to very high pressure for a short amount of time. This causes the rock to crack and cleave along the grain boundaries, creating a large number of fines but also forming microcracks in the larger particles. These microcracks create 'canals' to the gold ore particles trapped inside the ...
