An electrostatic fluidized bed powder coating apparatus including powder coating structure, such as a coating enclosure, hood or booth, and a powder fluidizing bed operatively associated with an electrostatic charging device. An enclosed powder accumulator is provided for collecting excess powder from the powder coating structure. A vacuum pump communicates between the powder coating structure and the powder accumulator and is operable by a source of compressed air for forming and controlling a cloud of powder emanating from the fluidizing bed and for transferring excess powder from the powder coating structure to the powder accumulator. In the preferred embodiment, the accumulator includes a cyclone housing. A powder reclaim feeder is disposed below and in communication with the cyclone housing and further communicates with a new powder feeder. A powder conveyor, in the preferred form of a rotating auger, transfers powder from the new powder feeder into the powder reclaim feeder and ultimately transfers the mixed powder into the powder coating structure.
