Abstract

At a centrifugal separator the centrifuge rotor has an inlet (24) to a separating chamber (4) for a fluid mixture of components to be separated, and means for removing of one separated component from another during the operation of the rotor. Said means comprise an outlet member (15) which is arranged to be entrained in rotation by fluid having been supplied to the rotor but which--at least intermittently--may be caused to rotate at a lower speed than said fluid. A channel (16) extends through the outlet member (15) from a point in the rotor, where the separated component is situated, to a reception place therefor. The reception place may be arranged either within or outside the rotor.
