Ball Milling Diagram Nanopowder Synthesis Chrome Ore Omani. ball milling method for synthesis of nanomaterials jun 15, 2012 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).
This energy is generated by high-energy planetary ball, shaker, or tumblers. The transferred energy depends on the vibrational or rotational speed of the balls, the number and size of the balls, as well as the ball size-to-powder mass ratio. In addition to this, it also depends on the milling atmosphere and duration of milling (Figure 2.3). 1231
