An effect of a grinding method, that is ball mill and high pressure grinding rolls HPGR, on the particle size, specific surface area and particle shape of an iron ore concentrate was studied. The particle size distribution was meticulously examined by sieve, laser and image analyses. To measure the specific surface area of particles, Brunauer-Emmett-Teller BET and Blaine methods were used.
Microcracks in HPGR materials result in improved penetration of leach solution into the grains and thus metal recovery. The objective of this work is to develop a better understanding of ores crushed by HPGR and cone crusher, in terms of microcracks and PSD, and assess the benefits of using HPGR

We have now launched HPGRs at Sections 2 and 3, completing the upgrade of the entire beneficiation plant. This will enable us to increase primary iron ore processing up to 37 million mty, up by 5 million mty in 2013, and become 100 self-sufficient in iron ore feedstock. Each HPGR unit replaced two conventional crushers.
Both standard HPGR lab scale test or industry measurement deliver high amounts of samples. Those samples contain a certain moisture range. For iron ore concentrates the value of 0-12 can be found on several worldwide installations with HPGR. Due to the high amount of sample of 100 kg the material has to be representably splitted.
Mar 28, 2020 The earliest industrial application of high pressure grinding rolls HPGR at comminution was in 1984 in the cement industry. Since then, the equipment has been widely applied in mining activities. Despite the rapid spread across the industry, several challenges are still present in the equipments application, especially considering the complex ore breakage behaviour reported for this
