    • Liquid to be atomized is uniformly sprayed on the inner surface of a hollow rotating cylinder, for example by means of one- or two-fluid-nozzles and is thus distributed on apertures provided in the cylinder wall. The rotation of the cylinder causes the liquid to flow outwards through the apertures. Droplets are generated when the liquid flows out of the apertures by laminary decomposition of the jet. The flow rate in each aperture lies in the range 1.0 200 of apertures having the diameter DA in the cylinder wall causes the flow rate of liquid through each aperture to be relatively low, so that a continuous laminary flow in each aperture is ensured even at low viscosities and technically useful total flow rates.

    • The liquid to be atomized is uniformly sprayed on the inner surface of a hollow rotating cylinder, for example by means of one- or two-fluid-nozzles and is thus distributed on bores provided in the cylinder wall. The rotation of the cylinder causes the liquid to flow outwards through the bores. Droplets are generated when the liquid flows out of the bores by laminary decomposition of the jet. The flow rate in each bore lies in the range 1.0 200 of bores having the diameter D.sub.B in the cylinder wall causes the flow rate of liquid through each bore to be relatively low, so that a continuous laminary flow in each bore is ensured even at low viscosities and technically useful total flow rates. Preferably cylindrical bores with a minimum length at least three times larger than the bore diameter are provided in the cylinder wall, with a narrow spacing in the range defined by 1.1
