The invention refers to a device for mixing chemicals into a pulp suspension, where a high-speed rotor (5) with an open center is mounted inside a mixing chamber (2). It is mainly characterized by at least one further high-speed rotor (5') with open center being provided, the areas covered by these rotors (5, 5') overlapping and the spacing between the axis of the rotors (5, 5') being selected so that the rotor arms (8, 8') extend almost to the center of at least one other rotor (5, 5').
