Product Features Energy-effective: Saving 30% 40% over the Equivalents. Endurance: Applied to materials with Moths' Hardness below Grade 9, since the milling effect only involves the impact and collision among the grains rather than the collision with the wall. Wide Grading Range: d97=2 15 um. No contamination. No rise in temperature. Inert gas can be used as media for milling of flammable and explosive material. It is widely applied to pulverize non-metallic ores, talcum, barite, kaolin, quartz, graphite fire retardant materials, high-grade grinding media, chemical, metallurgy, western medicines, traditional Chinese medicine, agricultural chemical and ceramics, as well as for such dry powders as highly adhesive and superfine pesticides.
