  • Patent number: 11135619
    Abstract: The ore intelligence sorting apparatus and method based on X-rays discernment includes a feeding unit with a toothed classifier, an X ray excitation unit with filter, a characteristic spectrum receiving unit with filter, a computer analysis and control unit with a central control unit, a spectral acquisition system, an industrial computer and an instruction output system, and a separator unit with a cylinder and a wear-resistant kick plate. The feeding unit is fed by a vibrating feeder and grading materials by a toothed classifier, and the measured ore is stimulated by the X ray excitation unit to produce a characteristic x ray spectra. The characteristic spectrum receiving unit receives the characteristic x ray spectrum which is then analyzed by the computer analysis and control unit, and a sorting instruction is output based on the analysis results. The invention is used for sorting magnetic or non-magnetic ores in a concentrator.
