ABSTRACT:
A roll sorter (110) includes two counter-rotating, circular cross-section, spaced rollers (112,114) defining a gap (124) therebetween. Particles 46 float on the rollers (112,114) within a sorting region (128) and are sorted by passing through the gap (124) or not so passing and being retained in the sorting region (128). The particles (46) are prevented from hopping or jumping out of the sorting region (128) by a circular cross-section rod 160 floating above the sorting region (128) on the rollers (112,114), so that sorting accuracy and throughput are not degraded.
