ABSTRACT:
A powder atomizer comprises a pan, and an element journaled for rotation about an axis. The pan partially surrounds the element, and therewith defines a venturi into which powder is fed. The venturi has an inlet and a spaced outlet. A motor rotates the element within the pan in excess of the speed required to throw powder from the element by centrifugal force and draws gas through the venturi, so that powder fed into the element is atomized and produces a uniform cloud of particulate material. A nonconductive element minimizes the electrical charge on the pan, and thereby the resulting agglomerization of particulate material at the outlet.
