Abstract

The excess material is extracted from the fluidized bed by a conduit suitable for the outflow of this excess. The extraction point in the fluidized bed is at the desired height for the bed, and extraction is controlled by a pneumatic seal. The excess material can be retrieved, cooled and possibly recycled in whole or in part after being crushed and sifted.
