  • Improving Energy Efficiency via Optimized Charge

    The U.S. mining industry operates approximately 80 semi-autogenesis grinding mills (SAG) throughout the United States. Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence typical gold or copper ore requires between 2.0 and 7.5 kWh per ton of energy to reduce the particle size.

     · There are a number of SAG mills in operation around the world with diameters reaching up to 40 ft. These operations continually invest in new technologies to improve their energy efficiency and capacity in their SAG circuit. Commercial SAG mill performance is determined by a large number of variables both mine-site variables and mill variables.

     · SAG mills on the other hand rarely approach the efficiency of a ball mill. Breakage mechanisms are not nearly so well defined and while it is possible to influence breakage rates in the mill by changes in mill speed ball load and feed size distribution manipulation of these variables will often fail to produce a power efficient circuit.
