Abstract
A method for coating surfaces of a powdered material includes forming a Coanda flow of a Coanda spiral flow of a powdered material by flowing the powdered material through a Coanda spiral flow forming passage or a Coanda flow forming passage by introducing a pressurized gas into the flow forming passage through a Coanda slit therearound, supplying the thus formed Coanda flow or Coanda spiral flow of powdered material into a further Coanda spiral flow forming passage, and atomizing a liquid coating material with a liquid gas and then directing the atomized liquid coating material into the Coanda flow or Coanda spiral flow of powdered material through a Coanda slit in the further Coanda spiral flow forming passage.
