A method as claimed in claim 1 in which the slurry is moved longitudinally through the centrifuge by feeding the slurry to the centrifuge at the large diameter end thereof under positive pressure and discharging a substantial portion of the slurry liquid from the centrifuge in proximity to or at the opposite end of the centrifuge.A method as claimed in claim 2, cone crusher for sale in which the slurry is accelerated to substantially the centrifuge rotational speed by substantially tangentially impelling said slurry towards the centrifuge periphery at one end of the centrifuge and angularly impelling the slurry during its travel through the centrifuge.A method as claimed in'claim 3, capturing solids settling in proximity to nozzles in each axially spaced plane for discharge from said nozzles, and separately collecting the discharge from said nozzles.
A novel mineral dressing centrifuge which comprises a vessel having a generally frusto-conical configuration with a large diameter end and a small diameter end mounted for rotation about its axis and having a plurality of circumferentially equispaced liquid discharge outlets through its peripheral wall in a plurality of axially separated planes extending from said large diameter end to said small diameter end, means for introducing a slurry of a particulate mineral mixture in a liquid generally axially into said centrifuge vessel, grinding media balls an impeller mounted concentric with the centrifuge at the large diameter end and adapted to rotate at the centrifuge rotational speed, said impeller having an axial chamber for receiving slurry from the feed pipe and having a plurality of substantially tangential outlets in communication with said chamber for equally distributing slurry towards the centrifuge periphery while accelerating said slurry to substantially the centrifuge rotational speed, means for maintaining the slurry at said centrifugal rotational speed, and means for separately collecting liquid streams discharging from each group of axially spaced apart outlets.
A centrifuge as claimed in claim 5 in which said means for introducing the slurry axially into the cenimity to the small diameter end of the centrifuge remote from the feed end adapted to discharge liquid at a rate relative to the slurry feed rate sufficient to maintain a positive longitudinal slurry flow within the centrifuge. A centrifuge as claimed in claim 7 in which an annular baffle is formed within the centrifuge between each adjacent set of axially spaced nozzles.
