The invention relates to a device for mixing chemicals into a fibrous material suspension in which there is a high-speed rotor (5) with an open centre in a mixing chamber (2). It is principally characterised in that there is at least one further high-speed rotor (5') with an open centre, the regions covered by said rotors (5, 5') intersect and the axial distance between the rotors (5, 5') is such that the rotor arms (8, 8') extend into the centre of at least one other rotor (5, 5'). |
