The decanter centrifuge has a bowl with a screw conveyor having a body (4) and a screw (7). Material to be separated into a light phase and a heavy phase is supplied through inlet ports (6) in the body, and the heavy phase is discharged through discharge ports in the bowl at one end of the conveyor. Between the inlet ports and the discharge ports for the heavy phase, the body of the screw conveyor carries a baffle (8c), generally shaped as a radial rib which forms a helical surface turning in the same direction as the screw (7). Owing to its shape the baffle actively contributes to the transport of the heavy phase, and with retention of the same gap between the baffle and the inner surface of the bowl, the gap area can be increased by increasing the axial length of the baffle.
