Abstract: A device and method for reliably and accurately detecting impurities in a bulk material comprising two opposing tunnel sections arranged such that a bulk material stream flows between or through the tunnel sections. At least one of the tunnel sections has a lighting means configured for indirectly illuminating the bulk material stream. Furthermore, an optical detector receives the light emitted from the illuminated bulk material. The lighting means and optical detector are configured about the tunnel sections such that the optical radiation optical radiation does not pass directly from the lighting means to the bulk material, nor from the bulk material stream to the optical detector An evaluation apparatus, responsive to measured data from the optical detector, identifies impurities in the bulk material. The invention moreover relates to a method for operating such a device.

Abstract: The invention relates to a device and corresponding method for sorting bulk material, in particular pellets, comprising a vibration conveyor apparatus and a feed apparatus, which feeds bulk material to the vibration conveyor apparatus and is examined for defects using a detector apparatus. Bulk material identified as being non-defective is deposited in a first outlet and bulk material identified as being defective is shorted out and deposited in.

Abstract: A device for measuring the diameter and/or the wall thickness of a strand that has a substantially circular cross-section and is guided through the device by guide means in the direction of its longitudinal axis includes at least one transmitter for transmitting terahertz radiation, at least one radiation optical system that conducts the terahertz radiation to a strand guided by the device, at least one reflector for the terahertz radiation arranged opposite a transmitter and behind the strand in the radiation direction of the terahertz radiation, at least one receiver for receiving the terahertz radiation reflected at the strand and/or the reflector, and an evaluation apparatus that determines the diameter and/or the wall thickness of the strand using the measuring signals received by the at least one receiver. A corresponding method is also described.
