A method for purifying a fluid from contaminating particles in a centrifugal separator by means of a separation aid which is of higher density than the fluid and which binds said particles, in which the centrifugal separator comprises a rotor body (1) caused to rotate about an axis of rotation (R), the fluid which is to be purified is led via an inlet (17) into a separation chamber (7) delimited by the rotor body (1 ), separated particles are discharged via a first outlet (25) and the fluid cleared of said particles is discharged via a second outlet (22), said fluid being mixed with an amount of separation aid, being supplied to the separation chamber (7) and being purified therein by the pollutant particles being bound to said separation aid, which separation aid is forced out by the rotation of the rotor body (1) to the periphery of the rotor body (1), a small flow of separation aid and particles bound thereto being discharged from the separation chamber (7) via the first outlet (25), and a flow of purified fluid being discharged from the separation chamber (7) via the second outlet (22), said separation aid and particles bound to it being conveyed along the inside of the rotor body by at least one conveying thread (16) towards and out through the first outlet (25). |
