- REPLACEMENT LEAF Interference generates a wave movement, the movement of which exceeds the diameter of the impeller.
- the mixer consisting of the impeller 1 and the rotor 21 functions as a hydraulic generator, as a result of which the liquid is mixed and moved dynamically, intensively, and solids of larger quantities can also be moved.
- the rotor 21 suitable for braking and for surface mixing can of course be replaced with any mechanical braking device. In this case, if the impeller and the accompanying suction line 17 are completely braked, the injectors are stationary, the effective range is maximum.

- the mixer can be used for numerous purposes.
- the impeller 1 will function in a manner known per se, while the other impeller 1 is the propellant and atomizes the conveyed medium drawn in from the environment in the form of a mixture onto the liquid surface.
- the mixer functions as a mixing and atomizing device.
- the mode of operation is as follows: As a result of the greater weight, that impeller 1 is immersed in the liquid, the suction connection 13 of which is connected to the suction line 17. Now there is liquid in the impeller 1 and in the suction line 17; the height corresponds to the surface of the liquid kit. While the liquid is completely displaced as a result of the rotational movement, it is tipped onto the surface by the buoyancy of the liquid. Now the liquid flows in at the open end of the suction line 17, as a result of which the impeller is tilted back. As a result of the tilting movement, the other impeller 1 is also partially immersed in the liquid; in this way it works as an atomizer, then it blows the mixture of the propellant, then it blows
