Product Description

I. Product Applications

A double‑deck, free‑fall‑type intelligent color sorter for powdered materials, offering high sorting accuracy, large throughput, low carry‑over, high yield, robust stability, and low operating costs. Its sorting range spans from 16 mesh to 140 mesh. It is primarily used in industries handling powdered materials such as sand for board production, high‑purity quartz sand, glass sand, calcium sand, photovoltaic sand, fused quartz sand, colored sand, natural sand, polymer materials, and edible salt.

II. Application Scenarios

● High-purity quartz sand: Trace black spots, discolored particles, and metallic impurities have been removed, with SiO₂ purity increased to over 99.9%.  
● Glass/plate sand: enhances whiteness and uniformity, reduces color spots and impurities, lowers the scrap rate of glass, and improves the gloss of glass sheets.  
● Colored sand/fused quartz: color grading and impurity removal enhance product value and meet the requirements of high-end decorative and industrial materials.  
● Other fine powders—such as calcium sand, colored sand, river sand, sea sand, natural sand, and edible salt—are precisely classified in the 16–140 mesh range.

IV. 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 a vast array of material types.  
● Camera Image Acquisition System  
Imported high-precision cameras 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.  
● Spray-type nozzle and valve-driven mode  
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 temperature, significant power loss, and shortened lifespan that arise from prolonged use of LED sources; ensures long-lasting durability under stable temperature conditions.  
● Feeding System  
An advanced material-feeding detection system is employed to ensure uniform material flow.  
●Caterpillar conveyor  
It employs a tracked conveyor system, delivering excellent color‑sorting performance and stable material transport, which effectively enhances the carry‑over ratio and sorting purity while also significantly reducing material breakage during the color‑sorting process.  
● Flexible modes with a 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.  
● Operating System – 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.
