In this research, nearly spherical CuO nanopowders (NPs) were synthesized in a highenergy ballmilling method at room temperature for different milling times (20 and 40 h) at dry medium. The structure, particle size, purity and morphology of the resulting CuO NPs were characterized by Xray diffraction, inductively coupled plasma and scanning electron microscopy (SEM) techniques. The results ...
High Energy Ball Mill is a versatile instrument because of the broad selection of accessories.

Calcined powders were high energy ball milled to prepare nanocrystalline powders by varying the milling speed from 100 rpm to 250 rpm with regular intervals of 75 rpm, fixing the milling time to 24h. The average particle size of the milled powders, as examined using TEM, shows a gradual decrease with increasing milling speed.

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.
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 ...
