The present invention is for a device for use by electrostatic powder coating. The device is intended for charging and application of powder. The device according to the invention has smaller outer dimensions than prior art devices due to a specially designed charging channel. This also makes it possible to obtain a large flow of powder and a smooth coating. The device is less subject to wear and maintenance and repair, e.g. exchange of worn parts is simple. The essential part of the invention is the mixing channel. In the embodiment shown in the figure the channel is formed by several small building elements, inner elements (2) shown in figure 4 and outer elements (4), as shown in figure 3. The building elements are held together by a central rod (3) and a surrounding outer tube (5). This in turn is surrounded by a slit (6) and an outer casing (7) shaped as an outer tube. The inlet (11) and the die (12) are also attached to the tubes (5 and 7). |
