application of hpgr mills in iron ore processing

Application Of Hpgr Mills In Iron Ore Processing. Application of hpgr mills in iron ore processing hpgr technology was introduced to the mineral processing industry in the mid1980s and has rapidly for the mining industry established itself as the convention in the comminution of cement clinker slag iron ore iron pellet plant feed and diamond ore.

Development of a Novel Grinding Process to Iron Ore

2020-3-28  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.
