Abstract
Apparatus and method for making small spherical particles comprising rotating a toothed disc at a constant speed. Heating means are provided to heat the spinning toothed disc so that when material from which the particles are to be made touches the toothed disc the material will melt and migrate to the teeth and form beads on the teeth. As the tooth disc rotates, centrifugal force causes the beads to be thrown off and form spheres as the falling beads cool off and re-solidify.
