HGM Ultrafine Grind Mill is an ideal equipment for grind non-explosive, non-flammable and brittle materials which Moh's hardness not more than six grade, like calcite, chalk, limestone, dolomite, kaolin, gypsum etc. Product fineness can be controlled between 400-3000 . This mill can be used widely in metallurgy, chemical combination, construction, mining, cement and other fields.    Performance Features   A. High efficiency and low consumption. At the status of the same material, power, and the same finish fineness, its production capacity per hour is 40% higher than other jet mill and mixing grinder. B. Durable. At the status of the same material, power, and the same finish fineness, HGM ultrafine mill wear life is longer than impact mill and turbine mill. C. Advanced grind device. Since there is no rolling bearings and bolts designed in the grinding space, it can avoid machinery breakdown problem due to long and hard use for bearing and airproof parts and sudden falling for rolling bears and bolts.       D. Excellent frequency and speed conversion device. It can easy to adjust granularity evenly. E. Wide fineness adjustable function. Finish fineness is adjustable between 400 to 3000 mesh
