Method of producing powder materials |
摘要 |
A method is provided for obtaining fine powders having narrow particle size range from non-conducting solids comprising the steps of: 1) creating an electrostatic charge on particles of a solid mixture formed by mechanical means, 2) grinding the mixture and neutralizing the electrostatic charge during grinding with a potential sufficient to create a corona discharge, 3) separating the powder according to particle size, and 4) collecting the finely ground finished powder product. The method is applicable to the manufacture of high quality cement powders. |
