Abstract: The invention relates to a device for a nozzle of a powder sprayer, which by way of example can be used for spraying for example color powder, which is electrostatically charged, or for disintegration and distribution of solid particles in powder form transported in a gas stream. By means of the present device, which is easy to operate and easy to connect with a transportation circuit respectively, the particle material is effectively disintegrated and distributed. The device has means (17; 51, 58, 75, 76) for the introduction of a gas stream under pressure in the stream of particles flowing through the device, whereby the powder during its forward transportation through the device under simultaneous compression is mixed with the gas rushing in.

Abstract: The invention relates to a powder sprayer with electrostatic charging capacity and by means of which in a simple and effective manner by way of example a coloring powder can be electrostatically charged, so that it will be completely charged all over the entire surface of the particles.The powder sprayer (1) comprises a number of curved charging ducts (6, 6') of long extension made of electrically non-conducting material which ducts are coated with an electrically conducting layer (7) along the main portion of their extension, said coated layer (7) being connected to a conductor (8, 10) intended by way of example to be connected with the ground, whereby a charging of the powder material takes place during its movement through said charging ducts (6, 6') after contact with the inner walls of the ducts (6, 6'), when the sprayer is in use.
