N.N. ZOUBOV ENGINEERS SMCE - SuperFine High Efficiency Air Classifiers are designed for precise classification of superfine products having a top size of 10 microns.
They are widely used in food, pharmaceuticals, limestone, cosmetics, plastics, and many other dry process materials.
As in the N.N. ZOUBOV ENGINEERS SMCE Whirlwind Air Classifiers, the feed discharges onto the rotating distributing plate and is hurled outward through the interior chamber.
The ascending airstream passes through a specially designed multiblade rejector rotating at higher speeds and permitting only the lower micron particles to follow the air currents to the fines chamber.
N.N. ZOUBOV ENGINEERS SMCE - SuperFine High Efficiency Air Classifiers are built in three sizes and two different types: Standard SuperFine High Efficiency Air Classifier where the air circulates in closed circuit within the air classifier and the Tangential SuperFine High Efficiency Air Classifier where the air with the fine product is discharged tangentially from the fan chamber and recirculated to the separator through an external cyclone collector.
In the Standard SuperFine High Efficiency Air Classifier, used commonly in the chemical and limestone industries, the change of fineness is achieved by adjustments of the number of the rejector blades.
In the Tangential SuperFine High Efficiency Air Classifier, an external control device permits changes in product fineness without the need to shut down to change rejector blades. It is used commonly in the flour milling industry to produce a variety of flours for the bakeries and cereal industries.
