Golden Inc is one of China’s leading optical sorting machine manufacturers, focusing on the research and development, production and sales of intelligent color sorting equipment. Headquartered in Hefei High-Tech Development Zone, China, the company’s products cover food processing, mineral sorting, renewable resource recycling and other fields, providing efficient and accurate sorting solutions for global customers.
Golden Inc’s optical sorters combine a variety of advanced technologies
- High-resolution camera system: The equipment is equipped with CCD, near-infrared (NIR) and multi-spectral cameras, which can accurately capture the subtle differences of materials, such as color, size, shape, texture and composition.
- Deep learning and AI algorithms: Some models have significantly improved sorting efficiency and accuracy by introducing artificial intelligence algorithms. For example, deep learning technology enables intelligent identification of complex materials such as wet and dry ores.
- High-speed pneumatic injection system: Use precise air injection technology to quickly eliminate unqualified materials while maintaining high throughput (processing capacity ranges from 0.5 tons to 50 tons per hour).
- Infrared and X-ray detection: For the sorting of ores and renewable resources, Golden Inc also uses infrared spectrum analysis and X-ray detection technology, which can identify the internal characteristics of materials, such as density and composition structure.
Golden Inc’s optical sorting equipment covers multiple industries. Common products include:
- Food sorting: rice color sorter, grain color sorter, tea color sorter, used to remove impurities. Their technology employs advanced optical sensors that can assess factors such as size, shape, color, and internal quality, enabling precise sorting and removal of foreign materials. This ensures food safety and minimizes food waste.
- Ore sorting：
Ore Color Sorting: Golden Inc’s mineral sorters leverage visible light and deep learning algorithms to identify and classify materials based on their optical properties. These systems are suitable for various applications, such as sorting metallic and non-metallic ores, quartz sand, and more. Both wet and dry ore sorting options are available, enabling flexibility for different mining conditions. Their systems can handle particle sizes ranging from powders to large stones (0.11–200 mm).
X-Ray Transmission (XRT) Sorting:Golden XRT technology detects variations in atomic density within ore, making it highly effective for sorting materials like copper, zinc, lead, and diamonds. This technique allows the separation of valuable minerals from barren or low-value rock early in the process. By pre-concentrating ore, Golden reduces energy consumption and processing costs while increasing the efficiency of downstream milling operations. - Recycling Sorting: Sorting equipment designed specifically for plastics and waste materials helps improve recycling efficiency and support sustainable development. Near-Infrared (NIR) Spectroscopy: Near-infrared (NIR) technology is one of the most widely used methods for sorting plastics. NIR systems use infrared light to identify the chemical composition of materials based on how they absorb or reflect light. This enables the precise sorting of various plastic types, such as PET, HDPE, PVC, and PP. NIR sorting is highly effective in mixed plastic streams, ensuring that different plastic materials can be separated accurately without the need for manual sorting.
