Sorting machine for particle mixtures - uses inherent resistance to movement to select shapes over sloping sorters

摘要

The sorting machine is for particle mixtures has a flat movable sorting base which is inclined by an acute angle to the horizontal. The mixtures are sorted according to the different rolling resistance or sliding resistance corresponding to the various shapes of individual particles. The particles are brought onto a sloping plane on which in addition to the force of gravity they are affected by a further force element which is inclined to the plane through the gravity vector and the slope of the plane. The sorting base is preferably a conveyor belt 19.20.21 which is approximately horizontal in the conveyor direction and inclined to the horizontal at right angles to it. The edges of the belt run horizontal in the sorting area where the material (3) to be sorted is transferred by means of a suitable scoop (15).
