Aug 07, 2019 Starting in the 1980’s, HPGR was first successfully implemented in the cement industry and is now used across a wide range of mining applications. Today, there are more than 200 machines operating in the mining industry around the globe, on more than 150 sites. These energy-efficient grinding machines are mostly used for processing iron, gold, copper and diamond ores, although …

literature on dry grinding with GAs is within the cement industry, fo-cusing mainly on their effect on fineness, energy consumption, and product properties (setting time and compressive strength) (Altun et al., 2015; Guo and Sun, 2017). There has been little discussion about the application of GAs in dry grinding that addresses some of the above

Dry processing at Vale. In the last 10 years, Vale invested almost R$66 billion in facilities and development of technologies for the dry iron ore processing production. Today, most of our iron ore production (about 60%) is through dry processing. The natural moisture processing is used at Caraj s and Serra Leste mines, at S11D Eliezer Batista ...

duty. In the iron ore industry, most of the machines are found in pellet feed applications. How-ever, there are a few notable examples where HPGRs are used for coarse iron ore grinding – in Chile, Mauritania and the USA. The first large scale attempt at applying HPGRs to harder and more abrasive copper and gold ores was in 1996 at Sierrita.
