ABSTRACT:
Electrostatic fluidized bed coating apparatus consists of an horizontal porous plate and a contiguous, vertical porous plate. Charged particles exiting the bed formed on the horizontal plate fall past the outer surface of the vertical plate, and are electrostatically recharged by ionized air issuing through it, thereby effectively extending the operative vertical length of the bed and substantially increasing coating efficiency.
