Working Princitple: Technological Empowerment for Precise Idenification 

      1. X-ray Emission and Penetration The X-ray source serves as the foundation of the sorting process. Based on the principle of electromagnetic radiation, it emits X-rays with specific energy. These X-rays radiate at the speed of light, with a portion penetrating vertically through materials on the conveyor belt along a preset path. X-rays exhibit strong penetrating power, and their absorption (attenuation) by different materials varies significantly—for example, the X-ray attenuation coefficients of glass, metal, and plastic differ markedly.

       2. Signal Conversion and Acquisition Below the materials, detectors play a critical role in signal conversion, primarily categorized into scintillator detectors and semiconductor detectors. For scintillator detectors, when transmitted X-rays strike a scintillator (e.g., sodium iodide crystals), the scintillator absorbs X-ray energy and converts it into visible light photons. These photons are then captured by a photomultiplier tube, which uses the photoelectric effect to convert photons into electrons, amplifying them through multi-stage multiplication to output an electrical signal proportional to the incident X-ray intensity. Semiconductor detectors operate on the photoconductive or photovoltaic effect of semiconductors. When X-rays enter semiconductor materials (e.g., silicon, germanium), electron-hole pairs are generated. Under an external electric field, electrons and holes migrate to different electrodes, forming a current signal that is amplified by a preamplifier into a voltage signal suitable for processing. Detectors collect these electrical signals point-by-point along the conveyor belt, creating a signal sequence that reflects the internal structure of the materials.        3. Data Processing and Analysis The collected electrical signals are weak and noisy, first converted into digital signals via an analog-to-digital converter (ADC) for computer processing. Specialized image processing algorithms—such as filtering, enhancement, and noise reduction—improve signal quality. Reconstruction algorithms (e.g., filtered back-projection) then transform 2D signal sequences into 3D or 2D tomographic images, visually depicting the materials’ internal structure. The computer analyzes each pixel in the images against predefined parameters and algorithms to calculate properties like density and composition. By comparing with a database of X-ray attenuation coefficients, it identifies foreign objects, defects, and material types. Upon detecting non-compliant items, the system rapidly locates and classifies them.

     4. Sorting Execution and Rejection Once identification is complete, the computer sends control commands to the actuator—typically a high-speed air valve device. Activated within milliseconds, the valve emits a high-velocity air stream to divert target materials into a waste collection area, while qualified materials continue along the conveyor belt. This seamless process, from X-ray generation to precise rejection, ensures efficient and accurate sorting.
