improving energy efficiency in sag mills grinding mill plant. 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.
