Abstract

Small particles to be sorted are entrained in a stream of fluid and particle differences are detected to control a sorter located downstream. The sorter is effective to switch the particle carrying fluid to one of two different paths determined by the particle differences to thereby accomplish the sort. A particle detector is positioned to detect the passage of particles through one of said paths in order to verify that the sorting operation has occurred.
