ABSTRACT:
An apparatus for discontinuous mixing of at least two substances, of which at least one is a liquid, includes a container and a mixer which is disposed in the container. The mixer has a rotor drivable at high speed and a stator, the rotor and stator are provided with teeth disposed on mutually concentric circles. When the teeth move past one another, shearing slots are formed. In order to reduce the energy input and to reduce the required mixing time and/or improve the mixing results, at least the radially outermost circle of teeth on the rotor is disposed outside the radially outermost circle of teeth on the stator.
