Abstract

Color sorter for granular materials consisting of a number of discriminating units arranged in parallel. The detection points of the corresponding classification units are placed at a distance from each other in a flat plane. Each discrete unit includes a truly vertical guide extension for routing the granular material so that it moves along a predetermined path through the detection point. Three detectors are positioned at the detection point at an angular distance of 120 degrees around a predetermined trajectory, and the operating deflector responds to a signal from one or more detectors representing the granular material. The placement of three detectors of one or a pair of discriminating units close to each other is likely to be the same as that of the detectors. Three detectors of another classification when three detectors of one classification are rotated 180 degrees exactly around a defined trajectory of one classification.
