AG and SAG mills. Autogenous (AG) mills look like ball mills and function in a similar way — with the additional assistance of lifting plates that line the inside of the cylinder — but they use large ore particles as the grinding media. If the ore is too hard or abrasive, a small charge of steel balls may be added to aid the process

SAG Mill Testing Test Procedures to Characterize Ore Grindability
Because grinding theories are imperfect and ore hardness can vary with size, grindability tests are designed to best represent the size reduction of the industrial equipment analysed. For that reason, it is preferable to design a primary ball mill from a rod mill work index rather than a ball mill index, because the industrial mill
