I see they sell so called high energy ball mills for making nanopowders, which is interesting to me, otherwise you need to do funny things to get nanodispersions. Are they legit? My understanding is that a ball mill typically has a so called critical angular rotation where it is effectively having the most balls in grind mode, and that this ...

Milling in planetary ball mills and other highenergy mills is a simple and effective method to obtain nanostructured powders, which are widely used in powder metallurgy. Nanostructured WCCo hard alloys derived from such powders have high hardness and wear resistance due to the extremely small diameter of the WC grains [ 1, 2 ].

Mg 2 SiO 4 nanopowders were prepared from MgO and SiO 2 mixtures by using a high energy ball milling method, combined with subsequent calcination at low temperatures. After milling for 30 h, pure phase Mg 2 SiO 4 nanopowders with an average grain size of nm were obtained at 850 °C, 300 °C lower than that required by a conventional solid state reaction process.
