Abstract
A cyclone separator (,) has an elongated vertical housing (,), whose upper section (,) is equipped with a carrier gas/product inlet (,), a separating wheel (,), and a carrier gas/fine product discharge (,). A lower section (,) of the housing defines an oversized product discharge (,). The housing (,) has a central axially extending built-in unit (,), which separates the cyclone carrier gas/particle flow stream, downwardly in a peripheral region, and upwardly in a central region. A lower built-in unit section (,) is joined to a cylindrical middle built-in unit section (,). An entry area of the middle section (,) is equipped with a constrictor (,) which with the built-in body forms a Venturi. Finally, a secondary air supply (,) enters into a lower inlet opening (,) of the lower built-in unit section (,) facing the constrictor (,). An injector effect is achieved which increases the suction, resulting in further improvement of the separating and sorting properties.
