Ball-milling – Nanoscience and Nanotechnology I
In mechanical alloying, planetary ball mill is commonly employed because it involves very small quantities of precursor powders. Thus, this system is most popular for use in research laboratories. Planetary mill includes one turn disc or table and around four bowls. The turn disc and the bowls rotate in opposite directions to each other.
