Development of a Novel Grinding Process to Iron Ore

 · 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 equipment s application especially considering the complex ore breakage behaviour reported for this process.
