ABSTRACT:
A power-efficient liquid-solid separating centrifuge is disclosed which has power recovery apparatus on the bowl-head of a rotary bowl including a plurality of liquid flow passageways in fluid communication with transfer ports in the bowlhead of the rotary bowl for receiving liquid separated from the slurry introduced into the rotary bowl. These passageways are configured and arranged to direct the flow pattern of the liquid exiting the liquid transfer port to discharge at a radially inward position relative to the liquid transfer port and to flow in a direction with a reduced velocity component in the direction of the rotation of the rotary bowl, thereby recovering power previously expended to accelerate the feed slurry.
