The procedure for electrostatic coating of objects has honeycomb electrodes at a high voltage that remove powder particles from a fluidised powder layer through the pressure difference between the bottom edge of the honeycombs and the top surface of the layer. These particles are charged up by passing through the honeycombs to form a charged powder cloud. To create the pressure difference, compressed air is blown through pipes into the honeycomb electrodes and an additional vacuum is formed. Additionally the immersion basin is joggled. The surplus charged powder particles fall back between the electrodes into the powder layer and charge this up as well.
