Jun 19, 2015· 25% reduction in mill ball consumption, equivalent to a saving of more than R$3 million per year on purchases of these inputs. 5% reduction in power consumption in the milling operation, equivalent to a saving of R$900,000 per year.

of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.

Consistent quality and maximum output with lower specific power consumption results in lower operating costs per unit of production. Optimization can also reduce the cost of liners and grinding media. ... Every element of a closed circuit ball mill system is evaluated independently to …

simply cannot produce a 10 micron product at any practical power consumption. In this case the IsaMill has extended the economic range of grinding from about 20-30 microns to 10 microns – enabling technology if a 10 micron grind is needed, as it was for the KCGM cyanide leach.
