Abstract

A feed accelerator system (10) for use in a centrifuge, the system comprising a conveyor hub (26) rotatably mounted within a rotating bowl (12) the hub including an inside surface and an outside surface. At least one feed slurry passageway is disposed between the inside surface (42) of conveyor hub and the outside surface of the conveyor hub, and at least one helical blade (24) having a plurality of turns is mounted to the outside surface of the conveyor hub. A vane apparatus is associated with the passageway and is disposed between two adjacent turns of the helical blade.
The vane apparatus may include an inwardly extending baffle (58) and/or an outwardly extending accelerator vane (122).
Alternatively, a U-shaped channel (84) may be associated with the passageway, the U-shaped channel including plurality partitions (142) attached to the discharge end of such channel so as to form a plurality of discharge channels and a flow directing and overspeeding vane (146) disposed within each channel, each vane having a different forward discharge angle.
