About jxsc mine machinery mineral processing 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 sagball 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.
Laboratory ball mill kg capacity kg capacity kg the typical application of hpgr in heap leaching will be replacing the conventional tertiary crusher. with the larger, super hpgr systems of the future, additional metallurgical options exist, shifting more of the crushing load to the hpgr. when processing leachable ores through an hpgr, micro-cracks are created.
