ore color sorter could remove impurities from valued minerals by color difference in processing plants. Details The mineral ore colour sorting machine could scan bulk material in free fall by means of a colour line camera. The respective data is evaluated by a freely programmable sorting software of an industrial computer by colour, brightness and size into good product and rejected parts. The computer passes this information to up to 500 fast and robust compressed air valves, each of which serves one compressed air nozzle. Rejected parts are evaluated by position, shape and size and blown out of the material flow. Depending on material, particle size distribution and the quantity of rejected material,different quantities may be sorted.
