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