Comminution 2012 Comminution accounts for approximately 30 to 40% of the energy consumed on an average mine site (DOE, 2007) and somewhere from 4 to 9% of Australia’s total energy consumption (Tromans, 2008). Additionally, if one includes the energy embodied in steel grinding consumables, this ma...

The Julius Kruttschnitt semi-autogenous grinding (SAG) mill model was developed by Leung in the 1980s and extensively updated to the variable rates model by Morrell and Morrison in 1996. Since then only minor upgrades have been incorporated in the version distributed in the JKSimMet simulator. A num...
