Planetary Ball Mills for Nanoscale Grinding
WEBMay 6, 2011 · A suitable tool for this method is a planetary ball mill, such as Retsch's PM 100, PM 200 or PM 400, which provides the necessary energy input. The common rules for size reduction to micron size do not apply for the nanoscale; with decreasing particle size, electrostatic and even molecular interactions increase, leading to particle ...
