Product Description

The Guxin pebble-specific color sorter is equipped with multispectral fusion technology and intelligent AI algorithms, accommodating raw materials of varying particle sizes from 5 mm to 150 mm. By capturing comprehensive material characteristics across the entire spectrum, the AI accurately identifies foreign colors, impurity stones, and defective particles, swiftly rejecting them with a sorting accuracy exceeding 99.9%.

I. Application Scenarios

● High-purity raw material processing  
Glass sand/photovoltaic sand: Removes foreign colors, impurities, and mica; purity ≥ 99.9%, enhancing glass transparency and strength. Slab sand/artificial stone: Ensures uniform color, eliminates discolored or off‑shade particles, and provides consistent particle size, improving the aesthetic appeal and mechanical strength of slabs. High‑purity quartz raw material: Separates quartz from pebbles and other minerals (such as slate and waste rock), purifying high‑silica pebbles for use in refractory materials and ceramic glazes.  
● Construction Aggregates and Decorative Stone  
Pervious pavement/landscape aggregates: Sorted pebbles in solid colors such as white, yellow, red, and black, with uniform coloration and minimal impurities, suitable for garden paving, tree pits, and water features. Exterior wall/flooring washed stone: Impurities, weathered material, and clay‑laden particles are removed to ensure consistent color and adequate hardness, enhancing the architectural texture. Concrete aggregates: Soft, weathered, and impurity‑laden particles are eliminated to improve concrete strength and durability.  
● Landscape Architecture and Cultural Creativity  
Landscape Design: Premium pebbles of various color schemes and particle sizes (2–5 cm) are carefully selected for use in rockeries, streams, and courtyard paving. Cultural‑Creative Products/Crafts: Carefully chosen pebbles free of discoloration, cracks, and with attractive natural patterns are used for carving, painting, and commemorative stones.  
● Recycling Resources and Tailings Utilization  
Riverbed/Tailings Recovery: Sorting high-value quartz and silica from riverbed pebbles and mineral processing tailings, turning waste into valuable resources. Waste Concrete/Brick Debris: Separating mixed pebbles for use as recycled aggregates and subgrade fill, promoting environmental sustainability while reducing costs.  
● Other special scenarios  
Filter media/water treatment: Removes impurities and soft particles, ensuring the hardness and purity of pebble filter media; used for water purification and wastewater treatment. Chemical industry/filler material: Sorts high-purity, low-impurity pebbles for use as chemical fillers and grinding media.

III. Technical Advantages

● Image processing  
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 capture  
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 suit different materials; addresses issues such as high temperature, significant power loss, and shortened lifespan that can arise from prolonged use of LED sources; ensures long-lasting durability under constant-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 both the carry‑over ratio and the purity rate while significantly reducing material breakage during the sorting process.
● 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 a professional manufacturer, an intuitive human-machine interface, and a clear, easy-to-read operation menu, combined with simplified settings, enable customers to quickly master the various functions of the color sorter.
