Abstract
Solid particles are formed from a liquid by rotating a slinger about a vertical axis within a chamber to sling liquid droplets from vertically spaced annular rows of cusps disposed on an outer periphery of the slinger. An air flow is established within the chamber, the air flow rotating in a direction opposite the direction of rotation of the slinger. The air flow opposes travel of threads formed between successively slung droplets to cause the threads to separate from the droplets and turn into dust particles which become entrained in the air flow. The dust particles can thus be collected separately from particles formed by the droplets.
