A centrifugal separator for separating a particle containing fluid, for example smoke gas or sludge containing water, into a relatively light fraction and a relatively heavy fraction containing particles comprises a drum-shaped rotor (1) with two opposite gable walls (2, 3), at least one spiral-shaped partition wall (5) arranged between the gable walls such that at least one spiral-shaped separation passage (6) with a central inlet end (7) and a peripheral outlet end (8) are formed in the interior of the drum-shaped rotor. The partition wall has a tapering portion (11), which tapers towards the outlet end of the separation passage and which has at least one elongate free edge (12, 13) spaced from the gable-walls, wherein the free edge is formed as a light fraction overflow also acting as a passage obstacle for heavy fraction. |
