Abstract
A process and a dispersion apparatus for shaping a powder cloud emerging from a powder spraying apparatus achieve large powder clouds and good electrostatic charging by directing control air in a tangential direction towards a powder/air stream flowing through the dispersion apparatus in an axial spraying direction. A helically accelerated movement of the powder/air stream in the direction of an outlet is achieved thereby.
