METHOD FOR GRINDING MATERIALS IN DRUM MILL AND DEVICE FOR EFFECTING THE SAME

摘要

FIELD: all industries requiring dispersed materials. SUBSTANCE: method involves sustaining space electrostatic charge in the material being milled in the course of the whole milling process. The device for effecting the proposed method features complete electrical insulation of its units from the ground and electrical mass classifier is made to divide the ground material into fractions 0.1-100 $$$. EFFECT: obtaining fine-fraction powder materials. 4 cl, 1 dwg
