ore grinding mill power consumption

Fine Grinding Technology for Mines and Concentrating. Stirred mills use an internal auger to agitate the feedstock ore which is fed into the mill as a slurry and grinding media sand ceramic balls which produces finer more uniform grind sizes with reduced energy consumption Grinding power requirements are strongly related to product size in microns and stirred mill technology has been...

Modelling SAG milling power and specific energy

Jan 01, 2015 It is also possible to use the −1″ fraction that shows a positive effect on the SAG mill throughput (the power consumption decreases, but the specific energy decreases more) because the mineral goes faster to the mill discharge, leaving a greater part of the grinding task to the secondary ball mills.

Energy Use of Fine Grinding in Mineral Processing

Dec 18, 2013 Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill’s energy budget. Overall energy use and media ...
