and ball mills, have almost become obsolete in the move to higher milling rates required to process lower metal grades. Grinding circuits with fully autogenous (AG) or semi-autogenous (SAG) mills, often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades.

Are rod and ball mills set to become obsolete?
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.
