Abstract

The present invention relates to a centrifugal separator (1) comprising a rotor (2) which is rotatable around an axis of rotation (R), the rotor (2) comprising a separation chamber (10) with an inlet (7, 9, 11) for a liquid mixture containing solid particles, at least one liquid outlet (18, 19, 20) for a separated liquid from the liquid mixture, and a solids outlet (22, 26, 27) for the separated solid particles, wherein a screw conveyor (3) is arranged to rotate inside the rotor (2) around the axis of rotation (R), at a different speed than the rotor (2), the screw conveyor (3) having at least one conveyor flight (3c) for transporting the separated solid particles in the separation chamber (10) towards and out of the solids outlet (22), wherein the conveyor flight (3c) is provided with wear resistant elements (23) arranged along its edge and the wear resistant elements (23) are spaced apart with an interspace (23a) between mutually adjacent wear resistant elements (23).
