Factors influencing direct separation of destabilised impurities in a fluidised layer of granular material

The results obtained from a study into the influences of certain technological factors on separation efficiencies of a fluidised layer of granular material (FLGM) are summarised. This study shows that the mechanism of interception of destabilised impurities on the surface of a granular medium corresponds to the mechanism of mutual particle aggregation of destabilised impurities. The efficiency of this process is influenced by the degree of destabilisation and degree of aggregation of the particles of impurities. The highest efficiencies are obtained when the particles of impurities enter a FLGM immediately after the completion of their destabilisation and their aggregation takes place entirely in the FLGM.
