Abstract

In a solid-jacket centrifuge drum for separating out a liquid phase, a weir is rotatable with the drum around an axis, is disposed in a path of the separated out liquid phase and has at least one channel for the separated out liquid phase. A choke plate regulates flow through the at least one channel in the weir and thereby the level of liquid inside the drum. The choke plate is stationary relative to the rotation of the weir and the drum and is axially displaceable relative to the weir to form a gap therebetween for the separated out liquid phase. The gap has a distance which is varied with the axial displacement of the choke plate.
