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.
