Abstract: The method involves a container (2) with a drain pipe (25). Air is introduced into the pipe through an opening and the adjustable air pressure controls the mass flow through the pipe from zero to a maximum value. The container is part of a powder spraying unit (1) and the powder is removed from a fluidised bed in the middle of it.
