Claims3
In a hydrocyclone having an upper feed section for introducing a slurry tangentially into said hydrocyclone and having an upper outlet for discharging water, and a lower separating section having a lower downwardly-directed outlet for discharging separated solids and water, the improvement comprising:
- a dewatering tube spaced below said feed section extending from said lower outlet into the space above said outlet to further reduce the water content of the materials discharged through said tube, sufficient to provide an underflow through said tube that is up to about 60 percent solids.
In a hydrocyclone having an upper feed section for introducing a slurry tangentially into said hydrocyclone and having an upper outlet for discharging water, and a lower separating section having a conical chamber terminating in a lower downwardly-directed outlet for discharging separated solids and water, the improvement comprising:
- a dewatering tube spaced below said feed section extending from said lower outlet into said conical chamber to further reduce the water content of the materials discharged through said tube, sufficient to provide an underflow through said tube that is up to about 60 percent solids.
