The Most Important Parameters Of Planetary Ball Mill Speed. Can not find a suitable speed, from the work efficiency is reduced, the effect becomes worse, and the result is that the material mixing, dispersion processing can not be successful, for example, in the process of cell crushing, mechanical alloying and other processes directly.
Nov 11, 2013 Nanopowders of Centella asiatica was produced using planetary ball mill by varying milling parameters such as milling time, mass concentration, and bead amount. Particle size analysis employing photon correlation spectroscopy was carried out to record the effect of milling parameters on the particle size produced. The morphology of milled powders was also analyzed using a field.
