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.
