Micronization technologies of mechanical methods

While material is micronized, its application performances will be improved because ultra-fine powder has some unique properties. Mechanical micronization technologies are mature and easy to enlarge on production scale. High production ability makes its manufacture cost lower. Mechanical micronization equipments are reviewed in this paper, especially fluid energy mill, and application foreground in national defence industry are also forecasted.
