ABSTRACT:
A feed accelerator system for use in a centrifuge, the system comprising a conveyor hub rotatably mounted substantially concentrically within a rotating bowl, and an accelerator including a cone-shaped inside surface disposed between an accelerator base and an accelerator small diameter section. The accelerator is secured proximately to its base within the conveyor hub so that the accelerator rotates with the conveyor hub. A distributor including a distributor surface having no sharp bends or junctions is secured to the small diameter section. A plurality of accelerator vanes are disposed on the cone-shaped inside surface and extend proximately from the small diameter section and terminate at a location on the cone-shaped inside surface proximate to the accelerator base so that an unvaned portion of the cone-shaped inside surface forms a smoothener section. A feed pipe having at least one discharge opening is disposed within the centrifuge so that the discharge opening is positioned proximately to the distributor surface at a stand-off distance. The stand-off distance, feed slurry flow rate, diameter of the feed pipe, location of the accelerator vanes proximate to the small diameter section, and number of vanes are selected to obtain overall maximum centrifuge efficiency.
