Abstract

A solid-jacket screw centrifuge is disclosed. The centrifuge has a rotatable drum with a horizontal axis of rotation which encloses a bowl with a rotatable screw, an inlet for introducing material to be centrifuged into the bowl, at least one liquid and at least one solid discharge, where at least the solid discharge is assigned a non-rotatable housing surrounding it, at least radially bounding a discharge chamber, where the discharge chamber is designed as a drying chamber for the solid matter and has axial walls and one or more walls in the radial direction. The housing extends axially parallel to the axis of rotation at most into the conical region of the drum or the screw.
