Air pressure spreading sifter - is fitted with ventilator and separating cyclones located outside sifting housing

摘要

Each separating cyclone is connected to the upper edge of the sifting chamber inside the sifting housing through a pipe socket and the cross section surface of the sifting housing is equal to a maximum of 0.7 times the sum of the cross section surfaces of the dividing off cyclones. The sifting chamber (2) is limited by parallel walls from the lower edge of the centrifugal system (8) up to the top edge of the chamber outlet. Pref. the o.d. of the scatter plate (4) underneath the centrifugal system is smaller than the i.d. of the sifting chamber. The inner wall of this chamber is formed as a cylinder.
