3. BALL MILLING Ball milling is a method of production of nano materials. Ball milling is a method of production of nano materials. This process is used in producing metallic and ceramic nano materials. This process is used in producing metallic and ceramic nano materials. These mills are equipped with grinding media composed of wolfram carbide or steel. These mills are equipped with grinding media composed of wolfram carbide or steel. Ball mills rotate around a horizontal axis,partially filled with the material to be ground plus the grinding medium.

5. The balls rotate with high energy inside a drum and then fall on the solid with gravity force and crush the solid into nano crystallites. The balls rotate with high energy inside a drum and then fall on the solid with gravity force and crush the solid into nano crystallites.

6. CONCLUSION The significant advantage of this method is that it can be readily implemented commercially. The significant advantage of this method is that it can be readily implemented commercially. Ball milling can be used to make carbon nanotubes and boron nitride nanotubes. Ball milling can be used to make carbon nanotubes and boron nitride nanotubes. It is a preferred method for preparing metal oxide nano crystals like Cerium(CeO2) and Zinc Oxide (ZnO).
