The decanter centrifuge comprises a screw conveyor having a body ( 4 ), which carries a screw comprising one or more flights ( 7, 7 ') and having a nominal transport speed varying along the longitudinal axis. An inlet ( 6 ) is provided in the screw conveyor for the material to be separated. The screw conveyor is provided with a baffle ( 8, 8 ') dividing the separation chamber in a substantially cylindrical separation part ( 17 ) and an at least partially conical discharge part ( 18 ). Immediately upstream of the baffle ( 8, 8 ') a transition part ( 19 ) is provided between the separation part ( 17 ) and the discharge part ( 18 ), the screw conveyor ( 3 ) having a bigger nominal transport speed in the transition part ( 19 ) than in the separation part ( 17 ) immediately before the transition part ( 19 ), the change of the nominal transport speed being established by a change ( 21 ) of the screw pitch. |
