A device in connection with a rotor (9) for the treatment of a liquid such as molten metal in a reactor (20) or similar. Gas and/or particulate material is supplied to the liquid, preferably via the rotor shaft (8) and through openings (18) from a cavity (16) in the rotor. The rotor shaft (8) extends up through the base of the reactor (20) and is arranged so that it may rotate inside a stator pipe (3) which extends up from the base of the reactor. The rotor shaft and the stator pipe extend through an opening (21) in the lower side of the rotor (9) and into the cavity (16) in the rotor. Expediently, the rotor shaft (8) is connected to the rotor (9) via a fixing device (13) inside the rotor cavity, while the stator pipe (3) ends in the cavity (16).
