Rotary atomizers - Wikipedia

Rotary atomizers work on the principle of centrifugal energy; this energy is used to produce a high relative speed between the fluid and air which is essential for atomization. A rotary atomizer comprises a rotating surface. This surface can be in the form of a flat or a vaned disc, a cup, or a slotted wheel. A basic rotary atomizer is displayed in the figure. The liquid first flows radially outwards in the disc and is then released from the disc's outer limits at a rel…
