Why HPGRs are revolutionising mill circuits

07/08/2019 HPGRs can handle a wide variety of ores and particle sizes, from fine pellet feed all the way up to coarse grinding of 75mm magnetite iron ore. Alongside their greater tolerance for ores of different hardness and variable roller speed, HPGRs promote greater flexibility in feed conditions and circuit design than traditional mills.

HPGRs Grind Out Larger Role in Plant Productivity E & MJ

Used commonly in cement production since the 1980s, HPGR technology was applied to iron ore and diamond processing in the following decade, and after the turn of the century established a firm foothold in nonferrous ore operations as well, with HPGR circuit installations in large concentrators at the Cerro Verde, Boddington and Morenci mines validating the technology for use in high-volume copper/moly

Opportunities Mineral Processing

In processing lines the combination of crusher, HPGR and IsaMill can force out the classical comminution line with crusher, SAG mill, ball mill and vertical stirred mills. The fineness requirements depend on the required liberation particle size for the flotation and on the classification process downstream of the comminution process.
