Apparatus for sorting objects according to size

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