Abstract
Improved centrifugal decanters with a screw conveyor for the continuous separation of solids-liquid mixtures are disclosed wherein the conveyor is provided with a feed arrangement for reducing the magnitude of mechanical vibrations of the centrifuge comprising a coaxially mounted feed distributor, generally trunco-conical in form, adapted to distribute into the conveyor, a solids-liquid feed stream falling into the distributor from a short stationary feed tube. The invention includes processes which use such improved centrifuge apparatus for continuous separation of solids-liquid mixtures into separate components by centrifugal action.
