  • Sorting installation and method for separating material fractions
    Patent number: 10245621
    Abstract: In order to achieve a higher material throughput and/or a higher sorting speed in a sorting installation (10) for use in plastics recycling, it is provided, in the case of an apparatus which is intended for separating one or more material fractions from at least one material stream of free-flowing bulk material and which has a directing device (12), via which the material stream is guided under the action of gravitational force, also has an optical sensing device (16) for the spectroscopic detection of composition- or condition-dependent properties of individual fractions (13) contained in the material stream, and additionally has a separation device (14), by which the individual fractions (13) contained in the material stream are separated mechanically in dependence on detection results of the optical sensing device (16).

  • Method and device for detecting and differentiating between contaminations and accepts as well as between different colors in solid particles
    Patent number: 6509537
    Abstract: The invention concerns a method and a device for detection of and differentiation between base materials, colors and contamination in granulate-like or tablet-shaped substances, characterized in that the substances are illuminated in a linear manner with a laser beam, the optical radiation re-emitted by the substances is spectroscopically analyzed, and the substances are classified and sorted into different groups.
