Abstract
A liquid accelerator system for use in a centrifuge, the system comprising a conveyor hub rotatably mounted within a rotating bowl, the hub including an inside surface and an outside surface. At least one feed slurry or wash liquid passageway is disposed between the inside surface of conveyor hub and the outside surface of the conveyor hub. A plurality of outwardly extending extensions is associated with each passageway. In the preferred embodiment, the extensions having an axis oriented parallel to and at forward angles to the radial direction of the conveyor hub at the passageway are U-shaped channels. The extensions having an axis oriented at reverse angles to the radial direction of the conveyor hub at the passageway are full channels. A plurality of partitions extends in a circumferential direction from the discharge end of each U-shaped channel and each full channel so as to form a plurality of discharge channels. A flow directing and overspeeding vane is disposed within each discharge channel and extends radially and circumferentially from each discharge end. Each flow directing and overspeeding vane includes a different forward discharge angle and is angled in the direction of rotation of the conveyor hub.
