Planetary ball mills 3. Attritor mills. These methods although cheaper than the chemical method but still are very high priced. Hence in this project we have developed a machine which will manufacture nanopowder cheaper than the above mentioned methods. A principle of high-energy ball milling is used in order to produce nanopowder
