An apparatus which operates with counter-rotating mixer elements, which are arranged coaxially to each other, serves to save on guiding fittings on the vessel walls of mixing vessels. In this case the exit spin of the one mixer element is wholly or partially compensated for by that of the other, which makes the corotation of the vessel contents adjustable. A component to be mixed in can optionally be added to the high turbulence zone between the mixer elements, since the shafts of the mixer elements are constructed to be hollow. To adjust the rotation of the vessel contents, the speeds of rotation of the mixer elements can be adjusted independently of each other.
