A SCALE UP MODEL FOR HPGR HARD ROCK GRINDING, p. 365-374. In: 38º Seminário de Redução de Minério de Ferro e Matérias-primas e 9º Simpósio Brasileiro de Minério de Ferro, São Luís - MA, 2008. ISSN: 2594-357X, DOI 10.5151/2594-357x-0038 ...
Importantly, Enduron HPGRs also provide significant improvements versus traditional tumbling mill technology with energy savings of up to 40% and in turn, a lower carbon footprint. This will be the fifth, similar-sized Enduron HPGR in the Pilbara region alone, which is a testament to its credibility in high capacity, hard-rock grinding."

The new modeling approach for HPGR crushing is based on population balance model. The breakage rate of the particles was defined as a function of specific grinding force and material characteristics. The model was developed for a wide range of data acquired from hard rock and cement grinding but only a few data was presented …
The first noteworthy HPGR application was at the Cyprus Sierrita copper mine in the USA in 1995 [4], even though the extremely abrasive ore prevented the achievement of economic grinding roll ...

The orebody contains a mixture of hard rock, softer material, and clays (sericite), in proportions that are expected to vary throughout the mine-life. The feasibility of a novel comminution circuit, using an autogenous (AG) mill/scrubber and parallel trains of cone crushers and high-pressure grinding rolls (HPGR) is being investigated.
This work proposes a systems optimization control model for energy management of a parallel crushing process made up with high-pressure grinding rolls (HPGR) machines. The aim is to reduce both energy consumption and cost through optimal control of the process and load shifting, respectively.
In service since the mid-eighties and used primarily in cement production, high pressure grinding rolls are increasingly being deployed as tertiary and quaternary crushers in mineral comminution circuits, dealing with tougher ores including iron, gold, copper and diamonds. HPGR technology uses inter-particle grinding to reduce particle size and …
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.

Over the past several years, the combination of higher energy and steel costs and the recent commercial deployment of high-pressure grinding rolls (HPGR) technology in hard rock mining have led many multinational mining companies to evaluate the suitability of HPGR technology for their particular comminution circuits. HPGR …
requires a population balance model for the HPGR. A suitable population balance model for HPGR grinding has been developed, and calibrated against pilot scale grinding …
By mid 1990s, HPGR installations were being used in minerals industry, mainly in iron ore pelletizing and diamond. This was followed by applications in hard rock grinding as copper, gold and platinum ore. The HPGR has been introduced to minerals industry as a replacement for tertiary crushers, SAG mills and rod mills.

As it is widely used to process hard and soft rock, construction waste, limestone, river gravel, granite, and basalt, the demand for HPGR is rising across the globe. High Pressure Grinding Roller (HPGR) Market Trends: At present, there is a rise in the demand for energy-efficient grinding solutions in the mining industry around the world.
The oversize of the flip-flow screen is fed into the HPGR with the −1 mm fraction accounting for 17.73 %, and the undersize proceeds to the downstream grinding circuit. The HPGR increase the −0.074 mm fraction from 8.03 % in the feed to 15.61 % in the discharge and the −1 mm fraction from 17.73 % in the feed to 42.26 % in the discharge.
