the correct power required to grind ore in a SAG mill, by developing ore hardness variability functions for the ore body to be mined. This paper describes the next step in the SAG design process, which is choosing a SAG mill to accomplish the required specified design performance.
Processing. Gold within the ore is very finegrained, ranging from 150um to less than 10um and commonly less than 40μm. The Cracow processing plant consists of a threestage crushing circuit, primary and secondary ball milling, preleach thickening, .
providing a 25% pebble circulating load. The current SAG Mill operation is still rated MW power at draw however has been operated at higher ball charges up to 18% and with 133 mm diameter grinding media. The Ball Mill was originally designed for 7,000 kW power draw, a with a maximum ball charge
The mathematics develops the power draw of a charge geometry and motion, and then applies a fitting factor k to convert the power draw of the mill charge into the observed gross motor power (the motor input). The highlysimplified formula is given in Equation 4: Gross power = noload power + k × (Cylinder motion power + Cone motion power) (4)
MinetoMill optimization is a total systems approach to the reduction of energy and cost in mining and processing. Developed at the Julius Krutschnitt Mineral Research Center in Queensland, Australia, the MinetoMill approach attempts to minimize energy consumption through optimization of all steps in the size reduction process.
SAG power draw survey tabulation This LibreOffice spreadsheet contains the raw data used to create Table 1 and Table 2 of the paper "An updated data set for SAG mill power model calibration", presented at IMPC 2016 in Quebec City, Canada in September, 2016.
Modern mills operate with load cells and mill optimizer''s which synchronize the mill weight, power draw, ore feed and weight with density control. Where optimizers are not used, the rule of thumb for a overflow ball mill is a ball load up to about 12 inches below the trunnion discharge this allows bed expansion by the slurry filling the voids ...

POWER OPTIMISATION. For the most productive milling operation it is often best to operate close to the maximum mill power draw. The powerload relationship is highly nonlinear and shifts around as the ore and steel load/liner changes. Traditional control and modeling techniques can therefore not be used. Mintek has developed a Power Optimiser ...
