1. A centrifugal separator comprising:
a bowl rotating in use around an axis of rotation, said axis of rotation extending in a longitudinal direction of said bowl, a radial direction extending perpendicular to the longitudinal direction; a conveyor arranged coaxially within said bowl and rotating in use around said axis of rotation, said conveyor comprising an acceleration chamber, a separation chamber being radially outwards limited by said bowl and radially inwards limited by said conveyor, said acceleration chamber being provided with a plurality of feed ports on an outer circumferential surface thereof for inlet of feed material into the separation chamber, each of the plurality of feed ports opening in said radial direction, and a feed accelerator arranged coaxially with said conveyor within said acceleration chamber and rotating in use around said axis of rotation relative to the conveyor at a lower speed than the conveyor, said feed accelerator having a discharge outlet for discharge of feed material through said discharge outlet into said acceleration chamber of the conveyor, wherein at least one of said plurality of feed ports extend a first axial area and said discharge outlet extends a second axial area, the first and the second axial area overlapping mutually such that feed material flows from the discharge outlet through the plurality of feed ports in direction having a radial and a circumferential component. |
