A Developing Method to Prepare Micro-Nanopowder by Incorporating Jet Milling and Electrostatic Dispersion

Abstract:

A new method to prepare micro-nanopowder with incorporating jet milling and electrostatic dispersion was presented in this study. The dispersivity of the powder could be improved during the process of jet milling by having the particles charged with identical charge. Both micro-nanopowders with high dispersion, calcium carbonate (CaCO3) and magnesium zinc ferrite (MgZnF) were prepared respectively. The theoretic studies on this method and the analyses on the effects of preparation parameters on dispersivity, showed that jet milling /electrostatic dispersion (J/E) method to prepare micro-nanopowder in the air without any additive is achievable. The charge voltage and air current pressure would strongly affect the characters of the powder. The charge to mass ratio (q/m) of both powders reached its peak under the charge voltage at 50 kV and air current pressure at 0.3MPa.
