<p>In wet gravity separation of solids according to specific gravity an outer depleted band partly overlies an inner concentrate band limiting yield and/or purity of separated concentrate. The overlying depletion layer is diverted outwardly from inner wall (15) relative to the concentrate band. Deflection means (20) cause a bow wave in descending slurry which fans out the concentrate aiding precise setting of downstream splitter blade (18) as well as diverting the overlying depletion band towards outer wall (13). The water which has become separated from the slurry due to centrifugal force can be re-homogenized with the remaining concentrate by restricted passage between deflector means (22, 26). </p> |
