ABSTRACT:
A conical sheath of air emitted from a vortex plenum adjacent the outer edge of a rotating bell spray apparatus is effective to optionally help atomize the coating material, and to carry the atomized material forwardly toward a confluence on the axis of the rotating head where tubulent mixing of the particles occurs, and the particles are sprayed forwardly for deposition in a uniform thickness film of a uniform population mix of particles sizes. Forward air and tangential air components are admitted to the plenum and are independently controlled so that different spray characteristics are obtained, the tangential air providing a swirl moment to the conical air sheath which enlarges the size of the deposited film pattern. The forward velocity determines the atomization ability of the sheath air and the particle velocity in the spray pattern. Electrostatic and non-electrostatic operations are intended.
