autogenous grinding mechanisms. HPGR, similarly, are generally tested with roller or piston press, to represent compression breakage. By opposition, the JKMRC approach to autogenous mill characterisation was to separate impact and abrasion mechanisms into two different tests (drop-weight and abrasion tests). Equally important is the need to
