Abstract: In order to explore solves the ultra fine powder to reunite the question in the air the new way,enhances the coal-series kaolin the functionalization use effect,This paper studied the electrostatic with the orthogonal experiment method to disperse to the coal-series kaolin grinding compound gathers group′s dispersible effect and the major effect factor.And with the high accuracy sizing test,the scanning electricity mirror and so on the advanced equipment has carried on the examination and the appraisal to the electrostatic disperser effect.The experimental result proved that,the electrostatic disperser method the coal-series kaolin grinding compound gathers the group to the disperser air in to have the remarkable effect.
