Ball Milling
Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

Tubular ball mill | Henan Deya Machinery Co., Ltd.
A survey of 40 industrial mills in China found that the maximum ball mill diameter in use was 7.9 metres and length 13.6 metres. Autogenous mills range up to 11 metres in diameter. The length-to-diameter ratios indicated in Table 1 for ball mills are for normal use, but for primary grinding the ratio could vary between 1:1 and 1.8:1.

A numerical analysis of the movement of balls in a vibration mill
Abstract. The grinding mechanism of a vibrating ball mill was examined by simulating the movement of the balls in a two-dimensional pot with circular vibration using a numerical calculation technique known as the discrete block method. The motion of the balls was also analyzed with the aid of video pictures superimposed on a computer …
