SEPARATOR FOR GRANULAR MATERIAL

摘要

The invention relates to a dynamic air separator which is used to separate granular powder materials into size fractions and which comprises a rotating cage (1). The inventive separator also comprises a chamber (2) which is intended for the recovery of fine materials and which is equipped with an outlet base. The aforementioned recovery chamber (2) is defined by a rotating casing (5) and is disposed co-axially in the extension of the aforementioned rotating cage (1), such that it can use the vortex created by said cage (1) for the cycloning of the material. Moreover, the recovery chamber (2) comprises openings in the casing (5) which enable the centrifuged material to move towards conduits (8) which are used to collect material located outside the chamber.
