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].
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)).
As demonstrated in Fig., the ball mill consists of a hollow cylindrical shell rotating around its axis horizontally or at a small angle with a horizontal line. Based on the rotation of the ball mill, the ball milling process is divided into various types: planetary, attrition, horizontal, rotatory, and vibratory mill.
