Ball mills rotate around a horizontal axis,partially filled with the material to be ground plus the grinding medium. 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. CONCLUSION The significant advantage of this method is that it can be readily implemented commercially. Ball milling can be used to make ...
