A ring and ball mill consists of two types of rings separated by a series of large balls, like a thrust bearing [20], that crush the material in between two particles. The attrition mill mechanically reduces solid particle size by intense agitation of a slurry of material being milled and coarse milling media [21].

The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills.
