Abstract
Method and apparatus for bulk sorting particulate material such as ore rocks. A conveyor belt carries the material in a continuous stream past a detector responsive to a required characteristic to produce a time sequence of detector signals dependent on degree to which material passing the detector possesses that characteristic. The material is projected from the downstream end of the conveyor belt into free flight trajectory and a deflector plate is moved across the face flight path so that material in some zones of the stream is deflected whereas material in other zones is not deflected. A control circuit monitors the detector signals and causes the deflector plate to move so that said zones are determined by the degree to which the material in them possesses the required characteristic.
