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)...Nano powder of aluminium-magnesium alloy was studied by various crystallographic techniques. XRD analysis of the nano powder was performed using Bruker D8 discover powder XRD machine. Figure 4 shows combined XRD patterns of bulk Al-Mg alloy and the nano Al-Mg alloy powder produced by EEW at a chamber pressure of 25 KPa.

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 ...The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling ...
