  • Combined Means For Separation Of Solids (AREA)

Abstract

Classifying a dry powder into fine and coarse fractions is disclosed. The separator comprises a housing with an inclined perforated bottom, a feed inlet and a coarse prod. outlet. A series of inclined perforated grids are arranged at intervals above the base and the device also has vertical partition walls with downwardly-sloping vanes. Air is blown through the base perforations, entrains some of the solids and eventually forms fluidised beds on various grids. By increasing the free area of successive grids, the air flow velocity through the various fluid beds is progressively reduced and the beds become concentrated with finer and finer particles.
