  • MEI Blog: Are rod and ball mills set to become obsolete?

    May 09, 2010· Going back to the HPGR/ Tower mill discussion, there seems to be a lot of evidence that the HPGR-stirred mill would offer a more energy efficient grinding circuit than a SAG/ball mill circuit. My query would be whether you will get the same liberation advantage from the HPGR when using a HPGR in combination with a stirred mill.

  • HPGR High Pressure Grinding Rolls

    HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
