Abstract

A screw-type solid bowl centrifuge for centrifuging material which has a tendency to foam. The centrifuge includes a centrifugal drum having discharge ports and a rotatable bowl jacket with a screw that rotates relative to the bowl jacket. Also included is a feed section having a central pipe arranged concentrically about the rotation axis of a drum for feeding the material to be centrifuged through a distributor into a centrifuge chamber between the screw and the bowl jacket. The feed section is an hermitical, closed system. Further included is a baffle plate arrangement that prevents foam or certain particles from escaping from one of the discharge ports.
