  • the first medium M1 and / or the second medium M2 can be at least partially charged and / or polarized or polarized or at least partially, for example, by electrodes (not shown) in the flow channel (1) and / or in the container 3 electrical field.
  • the movement of such charged or polarized particles can be influenced by an electromagnetic field (not shown), for example by capturing charged dust particles.
  • the powder in the container 3 and / or in the supply network can be fluidized by adding air or nitrogen. This improves the transport properties of the powder.
