Mechanical Centrifugal Air Classifiers
Air classifiers have the ability to separate powders as coarse as 80 mesh (180 μm), and as fine as 2–3 μm. The fineness of air-classified products is controlled by a precise balance among the quantity of rejector blades, the speed at which the rejector blades operate, the velocity of the airflow and the rate at which the material is fed.
