During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.
Working Principle. The Planetary Ball Mill has two or four ball grinding tanks installed on one turning plate. When the plate rotates, the tank axis makes planetary rotation in opposite direction and the grinding balls in the tanks grind and mix samples in high speed movement. The product can smash and blend various products of different materials and granularity with dry or wet methods.

Different kind of mills are suitable for grinding, mechanical alloying and mechanical milling such as horizontal mills (tumbler ball mill), stirred mill (attritor, Szegvari attrition mill 1), planetary ball mill, vibrating mill (tube vibrating mill, Sweco vibrating mill and shaker vibrating mill ( Spex is a labscale mill 3)).
Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. 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].
The planetary ball mill involves the generation of both shear and impact forces (Dash et al., 2016), which is commonly used in previous studies. The equipment arrangement of a planetary ball mill includes an eccentric grinding jar fitted on a sun wheel of which direction is opposite to the grinding jar (Fig. 2 a). The balls and grinding jars ...
