Abstract

The device for handling a flow of color powder particles comprises a housing (1) with an inner main channel (7) for moving a powder flow (8) from a powder unit (12) to a powder charging unit (13). In the housing is an ejector unit (15) for the supply of a first gas flow (11) to the channel at a first supply point placed upstream of the powder charging unit, but downstream of the powder unit. - The gas flow has a higher flow speed than the powder flow. The gas flow direction forms an acute angle (4) with that of the powder flow. Also in the housing is a diffusion unit (21) for feed of a second gas flow to the channel at a second feed point upstream of the powder charging unit but downstream of the ejector unit.
