Product Description

The core of the color-sorting solution for Gu Xin’s hematite-specific sorter is AI multispectral technology combined with a dual-layer conveyor belt, enabling both dry and wet processing.

I. Applicable Scenarios

● Processing target: Hematite (red/brownish-red), with removal of waste rock (light-colored or multicolored gangue such as quartz, calcite, mica, etc.), interbedded rocks, and low-grade ore.  
● Particle size range: dry separation, 3–150 mm; wet separation, 8–150 mm (suitable for feed material after crushing).  
● Core objectives: increase iron grade (e.g., from 45% to 58%+), reduce impurities (SiO₂, Al₂O₃), lower downstream grinding and flotation costs, achieve a recovery rate of ≥98%, and attain a color-sorting accuracy of ≥99.9%.

III. Core Specifications

● AI Multispectral System: 5,400-pixel high-speed full-color CCD plus infrared and ultraviolet multispectral imaging, capturing color differences, textures, and density variations.  
● Double-layer tracked conveyor: smooth material discharge, low breakage (breakage rate <1%), and anti‑clogging.  
● High-speed processing system: μs-level response, supporting “color sorting + shape sorting + quality sorting.”  
● Self-cleaning, dust‑proof design: optimized for dusty and humid mine environments, with stable operation from –20°C to +45°C.

IV. Sorting Principle

● Feeding and Dispersion: The raw ore is fed via a vibrating feeder to a double-layer conveyor belt, where it is evenly distributed in a single layer, preventing stacking and adhesion.  
● Multispectral inspection: As materials pass through the inspection zone, LED cold-light illumination and a CCD‑plus‑infrared system capture color, texture, and translucency. An AI algorithm then distinguishes hematite (red/brownish‑red) from waste rock (white/gray/variegated).  
● Intelligent sorting operation: The system classifies material as either qualified or waste. A high-speed solenoid valve (with a response time of less than 1 ms) injects compressed air (at 0.4–0.6 MPa) to blow the waste material into the reject chute, while the qualified hematite is discharged into the product chute.

V. Core Advantages

● AI deep-learning model: Trained to detect hematite’s reddish-brown gradient, surface oxidation, and dry–wet color variations, with an identification accuracy of ≥99.9%.  
● Low crushing and high throughput: dual‑stage tracked design with flexible conveying, achieving a breakage rate of less than 1%; capacity of 40–100 tons per hour, suitable for small and medium‑sized mines.  
● Extreme‑environment compatibility: dustproof and waterproof, operating from –20°C to +45°C, suitable for harsh northern winters and humid southern mining conditions.  
● Dual dry/wet operation: dry sorting (moisture <5%) and wet sorting (moisture 5%–15%), adaptable to varying raw ore moisture levels without the need for drying.  
● Low carry‑over ratio: Feed carry‑over < 2%, maximizing recovery.

VI. Technical Advantages

1. Image Processing System  
Cutting-edge DSP and FPGA processing technologies, combined with color‑ and spatial‑based multi‑mode complex algorithms, deliver “color‑plus‑shape” sorting capabilities tailored to diverse materials. With freely configurable modes, you can select from tens of thousands of material types.

3. Self-priming nozzle
Equipped with a professional high-speed air valve, it delivers rapid actuation, low power consumption, and an extended service life. It reduces air consumption, offers faster response, more precise impact, a lower carry‑over ratio, and higher throughput. Its service life exceeds 10 billion cycles.  
4. Light Source System  
LED optical design system, with multiple light source options to suit different materials. It addresses issues such as high temperatures, significant power loss, and shortened lifespan that can arise from prolonged use of LED sources, ensuring long-lasting durability under stable temperature conditions.  
5. Feeding System  
An advanced material-feeding detection system is employed to ensure uniform material flow.  
6. Crawler Conveyor  
It employs a tracked conveyor system, delivering excellent color‑sorting performance and stable material handling, which effectively increases the carry‑over ratio and sorting purity while significantly reducing material breakage during the color‑sorting process.  
7. 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.
