1. A device for sorting of raw, pre-treated or recycled bulk material, having individual components to be sorted, wherein the classification of the components to be sorted occurs according to empirical determined classification parameters, and the bulk material to be sorted out is diverted, comprising, in combination:

  • a bulk material conveyor for supplying the bulk material;

    a conditioning unit for wetting the bulk material;

    a breakdown unit for breaking down the bulk material into individual components to be sorted;

    a sensor device for detection of the characteristics relevant for the classification of the components to be sorted and for production of measurement data;

    at least one camera, which is included with the sensor device;

    an evaluation device connected to the camera for evaluating electronic measurements having at least one microprocessor or microcomputer for classification of the components to be sorted and for production of control signals by means of a control unit;

    an even diffused light emitting light source, which is associated with the camera;

    a pair of brushes situated within a housing, the brushes provided coaxially to each other and extending over the breadth of the housing, said housing open towards the bottom;

    a drive unit to coaxially displace the brushes relative to each other;

    a pair of bristle tufts provided within the brushes and arranged side-by-side with sideways separation with respect to the bulk material conveyor; and

    at least one light transmissive generally cylindrical body in which a light source is mounted, driven by at least one of compressed air and pressurized water.
