• Using stirred media mills in ore grinding - Technologie

May 24, 2021 Stirred mills are capable of grinding to particle size as low as 5 microns at a higher power intensity in stirred mills compared to conventional comminution equipment such as ball mills and tower mills. Despite the high power intensity, the overall power consumption of high speed stirred mills is lower due to short retention times. The major challenge encountered in the process of ore grinding is the use use of large size grinding media, which significantly affects the grinding

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
