AIR CLASSIFIER serves for dry classification of some mineral raw materials such as calcite, dolomite, marble, barite, feldspar, talc, lime, graphite, etc. The final product ranges as desired within the limits of 0.0 - 0.045 mm to 0.0 - 0.20 mm with a maximum of 3% of the rest. The capacity and fineness of grading depend on the shape and quality of the material and the use of the graded material. When making an inquiry or request for an order, state the data on the input material and the desired granulation of the fine product.
