high energy ball milling process in chennai

There are basically two methods of producing nano-scale particles: the "Bottom-Up" technique involves synthesizing the particles from atoms and molecules. With the "Top-Down" method the particles are reduced to nanometer size by grinding. Suitable tools for this method are planetary ball mills, such as Retsch's new PM-series grinders, which provide the necessary energy input.
