III. Technical Advantages

● Image and Algorithm Processing System  
Cutting-edge DSP and FPGA processing technologies, combined with color‑ and spatial‑based multi‑mode complex algorithms, deliver “color sorting + shape sorting” capabilities tailored to various materials. With freely configurable modes, you can select from tens of thousands of material types.
● Camera Image Acquisition System  
Imported high-precision camera lenses ensure clear, accurate imaging; an imported high-precision 5400-pixel high-speed linear full-color smart CCD is employed for high-definition recognition and rapid sorting.
● Self-priming nozzle  
Equipped with a professional high-speed air valve, it delivers rapid actuation, low power consumption, and extended service life; reduces air consumption, achieves faster response, more precise impact, lower carry‑over ratio, and higher throughput; with a service life exceeding 10 billion cycles.
● Light Source System  
LED optical design system, with multiple light source options to accommodate various materials; addresses issues such as high temperatures, significant power loss, and shortened lifespan that can arise from prolonged LED operation; ensures long-lasting durability under stable temperature conditions.
● Feeding system  
An advanced material-feeding detection system is employed to ensure uniform material flow.
● Free-fall type  
It employs a free-fall design, delivering excellent color-sorting performance and ensuring stable material descent, thereby reducing breakage during the sorting process and lowering maintenance costs.
● Wide range of applications  
Corresponding operating modes have been designed for different materials, enabling a single machine to perform color sorting on various types of materials.
● Simple and easy to use  
Touchscreen displays from professional manufacturers, an intuitive human–machine interface, a clear and easy-to-read operation menu, and simplified settings enable customers to quickly master the various functions of the color sorter.
