Developments in HPGR technology

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.
