In our Pulverizers, following cooling, sifting and drying, the packed air will create supersonic air-circulation via nozzle then the air-circulation will rip in the crushing container. At the base area, specific material will be carried by accelerated air-circulation, create harsh collision attrition as well as shearing to be performed superfine-ground. In addition, the crushed material in our Pulverizers will be carried to the grouping-sections with the updraft. The fine powders and coarse particles will be distinguished by centrifugal pressure of draught of blower and grouping wheels.
