This is a device for mixing building materials and liquids, having a mixing vessel, a mixing element rotating in the mixing vessel, a central mixer shaft for the mixing element and a feed line for the particular liquid. The mixer shaft is mounted in a coaxial stand pipe. The feed line for the liquid is connected to the stand pipe. Within the mixing vessel, the stand pipe has outlet orifices for the liquid, so that homogeneous mixing of the building materials and the particular liquids is achieved in the same way as continuous cleaning and consequently low-wear mounting of the respective shaft end of the mixer shaft. <IMAGE>
