Abstract
In centrifuges for separating solids-liquid slurries and which discharge concentrated solids through nozzles at the periphery of the centrifugal bowl or rotor, it is necessary to maintain a feed or influent rate at least as great as the nozzle discharge rate. According to the present invention, this is accomplished by driving from the centrifuge drive train a pumping means for returning concentrated solids from the nozzles to the centrifuge for recycling through the bowl.
