Steps in ball milling method; 1. As the name suggests, the ball milling method consists of balls and a mill chamber. Therefore over all a ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum).

Ball milling is a top-down technique to form micro to nano scale materials, by inducing heavy cyclic deformation in materials. Ball milling is nowadays widely used for the preparation of nanoparticles because of its simple operation, use of relatively inexpensive equipment and its applicability to essentially all classes of materials (Koch 1997
