In the metal recycling line, the optical sorter is the core equipment for efficient metal sorting, and its advantages are as follows:
1. Accurate identification and sorting of metal types
Using the unique optical properties of metals (such as X-ray fluorescence spectrum, reflectivity, color characteristics, etc.), quickly distinguish different metals such as aluminum, copper, iron, stainless steel, and precious metals.
- For example: detect the metal element composition through XRF (X-ray fluorescence) technology to accurately identify copper alloys and aluminum alloys; distinguish stainless steel from ordinary steel through hyperspectral imaging.
2. Improve metal recovery rate and purity
- Separate target metals from mixed waste (such as scrap car fragments, electronic waste, and construction waste) to avoid the inefficiency and omissions of manual sorting.
- Case: In the aluminum recycling line, the optical sorter can increase the aluminum recovery rate to more than 90%, and control the impurity rate below 3% (such as removing non-metallic impurities such as plastics and stones).

3. Realize automated and large-scale sorting
Replace traditional manual sorting or single technologies such as magnetic separation and eddy current sorting, adapt to the needs of large-scale industrial production, and the processing capacity can reach tens of tons per hour.

The specific functions are reflected in the following aspects:
1. Efficient identification and sorting of metal substances
Optical sorting machines use technologies such as X-ray fluorescence (XRF), X-ray penetration (XRT), and near-infrared spectroscopy (NIR) to accurately identify the metal components in urban garbage:
XRF technology: It can quickly detect the types of metal elements (such as iron, copper, aluminum, zinc, etc.), and separate metals from non-metals through characteristic spectral analysis, especially suitable for recycling high-value non-ferrous metals (such as scrap copper and scrap aluminum).
XRT technology: It uses the difference in X-ray penetration to distinguish metal density and internal structure, such as separating heavy metals (lead, zinc) and light metals (aluminum, magnesium) from mixed garbage, and even accurately sorting alloy materials.
Visible light and near-infrared technology: Through visual features such as metal surface gloss and color, it assists in identifying cans, metal fragments, etc., and combines with other technologies to improve sorting efficiency.
Function: Efficiently separate metals mixed in domestic garbage, improve metal recovery rate (such as aluminum recovery rate can reach more than 95%), and reduce resource waste caused by landfill or incineration.

2. Accurate sorting of non-metallic recyclables
In addition to metals, optical sorting machines can also perform fine sorting of non-metallic materials such as plastics, glass, and paper:
Plastic sorting: Use near-infrared spectroscopy technology to identify different types of plastics (such as PET, PE, PP, etc.), and classify them according to the differences in spectral fingerprints to help plastic recycling.
Glass sorting: Use visible light to detect glass color (such as colorless, green, brown) and impurities, remove glass containing metal or other contaminants, and improve the quality of recycled glass.
Paper and fabric sorting: Based on color, light transmittance and other characteristics, separate paper (such as newspapers, cartons) from fabrics, leather, etc. to improve the purity of paper recycling.
Function: Promote the high-value utilization of non-metallic recyclables and reduce the interference of "mixed garbage" on subsequent processing links.
