Abstract
A separator for continuously separating comparatively small particles of light bulk density such as, for example, expanded polystyrene x-beads from unexpanded polystyrene beads produced by an expansion process, preferably including a vibrating screen of a mesh size for passing smaller particles, but not larger particles, and a pulsed pressure differential across said screen for drawing smaller particles through the screen and for clearing the screen.
