Pinion On Sag Mill
Size Reduction and Energy Requirement - ScienceDirect
E SAG = SAG mill pinion energy (kWh/t) M = mass of mill ore charge (4.5 litres) This equation estimates the pinion energy to grind from a feed size, in the full size mill, of 80% passing 152 mm to a ball mill transfer size of 80% passing 1.7 mm. A change in transfer size can be accommodated between 0.4 and 3.5 mm by an adjustment using the Bond ...

Comparison of ore hardness measurements for grinding mill ...
Since the reproducibility of the SAGDesign tests is excellent, these results were used for the mill design. SAGDesign results have the added advantage of giving the required pinion energy to grind the ore to 80% passing 1.7 mm (SAG test) and the energy to grind from T80 1.7 mm to 80% passing 200 microns, the selected grind.

Firstly, there was a serious flaw in the power configuration of the SAG mill and ball mill (both rated at 6000 kW with a single pinion drive). The capacity of the SAG mill was not fully utilized, as the actual operating power draw was only 3358 kW. This meant it was only operating at 56% of its maximum power, providing large room for improvement.
