Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.

Both the SAG mill and ball mill are each driven by two gear units. Because, on a conventional drive variant, only one engagement per pinion with the girth gear is possible per side, an economic power limit of about 8 MW per drive is in effect. With the DMG2 gear units, Siemens said this limit expands to as much as 12 MW per drive.

After mill-to-motor speed synchronization, multi-plate clutches can also provide a level of protection during torque overload conditions in the mill by slipping if an unforeseen load spike occurs. This slippage protects the mill's pinion gear, ring gear and gearbox (if installed), which are all expensive items with typically long lead times.
