ABSTRACT:
An apparatus and method for utilizing and controlling finer particles in a powder coating system returns the finer particles to the spraying apparatus to be sprayed on parts by the system. Finer particles are continuously removed from the system by application onto parts, and the accumulation of fines is thereby prevented. The finer particles may be sprayed through specially adapted spray guns, which also permits the utilization of the special advantages of spraying fine powder materials. By removing fine powder particles from the system before they build up, the present invention improves the powder coating operation in various respects.
