The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.

Apr 29, 2011 · The mechanical milling was performed in a horizontal oscillatory mill (Retsch, PM 400) operating at 25 Hz. The mixture ratio of steel balls and ZnO powders was around 15:1 by weight percent. The milled materials were used directly with no added milling media. Five balls were kept in each cell along with 10 g of the sample powder.
(planetary ball mill, mixer ball mill, vibration ball mill, .). • The scale of reaction determines the size and the type of ball mill. • Vessels for laboratory vibration ball mills are normally restricted to a volume of 50 cm3.
