Benchmarking: Ball Mill Power Draw - Santa Rita

Latchireddi, S. & Faria, E., Achievement of High Energy Efficiency in Grinding Mills at Santa Rita, Proceedings of the Canadian Mineral Processors Annual General Meeting, Ottawa, Canada, January 2013.

Faria, E. & Latchireddi, S., Commissioning and Operation of Milling Circuit at Santa Rita Nickel Operation, Paper #137: Proceedings of the International Autogenous Grinding, Semiautogenous Grinding and High Pressure Grinding Roll Technology Conference, Vancouver, Canada, September 2011.

  • Ball mill dimensions 20 ft diameter by 28.4 ft effective grinding length
  • Induction motor size 5800 kW (with gearbox and pinion)
  • Rubber lining (assume 8 inch effective thickness)
  • Ore density: 3.23 kg/L (closest sample usable for modelling is 3.10 kg/L)
  • Mill speed not given, assumed to be 74% critical
