ABSTRACT:
The dryness of the coarse solids fraction discharged from a spiral classifier is improved by the provision of a secondary coarse particles discharge in the side wall of the classifier tank upstream of the primary coarse particles discharge. Part of the coarse fraction is removed from the process stream through the secondary discharge thereby relieving the load on the raking mechanism and facilitating the liberation of entrained free moisture from the coarse material remaining in the classifier tank.
