A system for atomizing and dispensing powder comprises a fluidized powder bed for entraining the powder fluidized in a bearing air stream, a dispenser, and a motor for rotating the dispenser. The dispenser has a somewhat bell-shaped interior. The motor has an output shaft having a first passageway extending lengthwise thereof. A feed tube extends through the first passageway. The fluidized powder is fed to an end of the feed tube passageway remote from the dispenser to be supplied through the feed tube to the interior as the motor rotates the dispenser. A diffuser is mounted within the interior. A discharge slot is defined between the dispenser and an edge of the diffuser. The feed tube is mounted so that it does not rotate with the output shaft. The diffuser includes a back side facing the interior and bounded by the edge. The back side includes a generally part-spherical concavity into which the fluidized powder is directed from the feed tube.
