Abstract

Jet milling is an innovative method to prepare micropowder with high efficiency and pureness, while the particles obtained through this way exhibit a prominent agglomeration due to the electrostatic attraction caused by friction of particles during jet milling progress. Recently, we have developed a new method to prepare micropowder by combination of jet milling and electrostatic dispersion. In this paper, both fine powders of calcium carbonate and talc were produced by J/E method, the particle size and its distribution were evaluated by SEM and LPSA as well. The results of our research reveal that the dispersion state of the micropowder thus prepared is influenced by its properties and the combined process is effectiveness in powder pulverization and dispersion.
