Abstract
In a centrifugal separator for separating solid particles from a liquid, a centrifugal rotor ( ) has two axially separated end walls ( ) and a surrounding wall ( ) arranged therebetween. The end walls ( ) and the surrounding wall ( ) surround a separation chamber ( ) in which there are arranged separation discs ( ) and one or more conveyor screws ( ) for axial transportation of separated solid particles. According to the invention the end walls are connected with each other through a central member ( ), which is dimensioned in a way such that during the rotor operation it will take up a substantial part, preferably at least 80%, of the forces acting axially on the end walls ( ) as a consequence of centrifugally generated pressure of liquid present in the separation chamber ( ).
