Abstract
A roll (110) sorter includes a pair (111) of counter-rotating rollers (112,114) separated by a gap (124). A sorting region (128) is defined by the gap and the facing roller surfaces (130,132). Particles (46) fed into the sorting region float on the rollers and are sorted into two groups, those that pass through the gap and those that cannot pass through the gap. The accuracy of the sorter is increased by associating a metering facility (220) such as a gate (222) with the sorting region. The metering facility limits the number of particles which can simultaneously enter the sorting region. Typically, the particles enter and move along the sorting region one-at-a-time and in single file.
