Abstract

An electrostatic spraying apparatus for applying powder to housings of refrigerators or the like has a disk-shaped sprayer which is rotated about a vertical axis and the upper surface of which receives a stream of powder through the slot-shaped orifice of a rigid or flexible conduit at an angle of 5 DEG -35 DEG . The upper surface of the sprayer carries radial agitating blades for air to thus reduce the speed of powder which creeps radially outwardly and is dispersed at the circular spraying edge of the sprayer. The orifice discharges the stream in the general direction of the spraying edge and is closely adjacent to the blades and to the periphery of the drive shaft for the sprayer.
