A centrifugal separator includes a rotor which is rotatable around an axis of rotation. The rotor includes a separation chamber with an inlet for a liquid mixture containing solid particles, at least one liquid outlet for a separated liquid from the liquid mixture, and a solids outlet for the separated solid particles. A screw conveyor is arranged to rotate inside the rotor around the axis of rotation, at a different speed than the rotor. The screw conveyor has at least one conveyor flight for transporting the separated solid particles in the separation chamber towards and out of the solids outlet. The conveyor flight is provided with wear resistant elements arranged along its edge and the wear resistant elements are spaced apart with an interspace between mutually adjacent wear resistant elements.

A centrifugal separator comprising a rotor which is rotatable around an axis of rotation, the rotor comprising a separation chamber with an inlet for a liquid mixture containing solid particles, at least one liquid outlet for a separated liquid from the liquid mixture, and a solids outlet for the separated solid particles, a screw conveyor being arranged to rotate inside the rotor around the axis of rotation, at a different speed than the rotor, the screw conveyor having at least one conveyor flight for transporting the separated solid particles in the rotor towards and out of the solids outlet, the conveyor flight being provided with wear resistant elements arranged along its edge, characterized in that the wear resistant elements are spaced apart with an interspace between mutually adjacent wear resistant elements.
A screw conveyor for a centrifugal separator, the screw conveyor being arranged to rotate inside a rotor around an axis of rotation at a different speed than the rotor, the screw conveyor having at least one conveyor flight for transporting separated solid particles in the rotor towards and out of a solids outlet, the conveyor flight being provided with wear resistant elements arranged along an edge thereof, the wear resistant elements being spaced apart with an interspace between mutually adjacent wear resistant elements.
A support device for a centrifugal separator, the support device comprising a holding member attached to a rotor and disposed at a central part of a solids outlet, the holding member and a tip of a screw conveyor being configured to cooperate in such a manner that the holding member rotatably receives and supports the tip of the screw conveyor to secure a clearance between the wear resistant elements on a conveyor flight and an inside wall of the rotor.
