There were and still are more hard-rock HPGRs in the pipeline as well as the completed installations, indicating that the potential E&MJ mentioned at the start of 2006—for HPGR technology to impact comminution as much as autogenous and semi-autogenous milling did—is being realized (E&MJ, January/February 2006, pp. 60-64).
Oct 01, 2009 1.. IntroductionHigh-pressure grinding rolls (HPGR) technology has struggled for acceptance into the hard-rock mining sector, has had many advances in this sector, but is still regarded as an “immature” technology (Bearman, 2006).It has been applied to progressively harder, tougher and more abrasive materials, generally successfully, but not without some problems (Morley, 2006).
Our innovative approach to HPGR. Our grinding technology is backed by continuous research and in-house pilot scale HPGR test facilities. This results in superior equipment efficiency and reliability, providing a solid basis for circuit design and scale-up.

Abstract This paper summarises test results that were used to validate a model and scale-up procedure of the high pressure grinding roll ... high pressure grinding rolls (HPGR) has ...
Nov 27, 2019 Results from the roll mock-up helped with customizing the procedure and equipment for measurements on actual lab-scale HPGR roll. Equipment, Material, and Methodology HPGR Roll Mock-Up. The HPGR roll mock-up was an assembly of a cylindrical aluminum roll, which was fitted to a shaft and housed in an aluminum structure for free rotation.

Jul 13, 2016 HPGR is typically used in a third-stage or fourth-stage crushing application ahead of grinding. You could always try to build a circuit doing 45 m classification, but I suspect your circulating load would be overwhelming. Most HPGR applications in hard rock …
EDEM, a DEM based software, was used to model the pilot scale HPGR unit and single particle compression test was used to evaluate the particle breakage and then used as an input parameter for the simulations. The results obtained from the simulation were then validated with the results from the pilot scale tests.
