The growing demand for ultrafine powders, coupled with stringent quality requirements, calls for continuous improvements in all aspects of fine particles production. Stirred ball mills are used in ultrafine grinding because of their high unit outputs, while the low amplitude vibro-energy mills are used because of their low specific energyStirred media mills are increasingly replacing ball mills for fine and ultrafine grinding, typically having around 30–40% less power consumption than ball mills when grinding to the same product size [8]. and the other is an adaption of a breakage model developed for impact mills.
