Abstract:
1. A system for the characterization of grinding material in a grinding plant, the system having: an irradiation section for passing through at least one part of the grinding material stream, wherein the irradiation section has at least one irradiation means for irradiating particles in the at least one part of the grinding material stream using electromagnetic radiation; and a detection section for passing through the at least one part of the grinding material stream, wherein the detection section has at least one detection means for detecting electromagnetic radiation emitted by particles of that part of the grinding material stream which is conveyed through the irradiation section; wherein the detection means has an imaging system and a color image sensor, adapted such that the particles can be imaged onto the color image sensor using the electromagnetic radiation they emit, wherein the color image sensor has sensor pixels for the spectrally selective detection of the electromagnetic radiation imaged onto the sensor pixels and the detection section comprises at least one illuminant or a combination of illuminants, which is/are configured and arranged such that the grinding material particles can be detected with a combination of transmitted light and reflected light.
