Stirred Mills are predominately used in industry for regrind, fine and ultra-fine grinding applications, as they have been proven to have superior performance compared to traditional tumbling mills. Stirred mills are more efficient, due to a very high number of stress events per unit time and unit volume, at the appropriate stress intensity, compared to a ball mill.
