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 ...

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

Jayasundara et al. (2012) and a recent study on HIG mills (Heath et al., 2017) also proved that the size of the grinding media influenced the power draw of the mill. Cleary et al. (2015) focussed in their computational study on the force balances and showed that the power draw of the stirred media mill increased with the grinding media size.

The effect of ball size and interstitial filling on the performance of dry ball mill grinding was investigated for a limestonetype brecciated uranium ore. The optimum grinding was obtained with the combination of different balls ( mm) and interstitial filling of 50% (20% ball filling ratio at fixed material filling ratio = 4%). The net power consumption in a ball mill is ...
