Since the 1990s, intelligent ore sorting technology has been researched internationally, achieving theoretical breakthroughs. Companies such as Gunson Sortex (UK), Outokumpu (Finland), and RTZ Ore Sorters have developed and produced over ten industrial models of photoelectric and radioactive sorters. These have been successfully applied in the sorting of non-ferrous and precious metals. However, their high cost, low sorting accuracy, and limited processing capacity have restricted their widespread use.
In China, mineral resources are primarily low-grade, yet abundant. Efficiently pre-discarding waste to enhance subsequent grinding and beneficiation efficiency while reducing processing costs is crucial for the mining industry. Huate’s independently developed XRT series intelligent sorting machines address these needs by utilizing differences in X-ray transmissivity and surface characteristics of mineral components. Advanced AI algorithms, combined with dual-energy X-ray transmission and image recognition technology, and high-pressure air jet devices enable precise mineral sorting.
Applications and Benefits in Various Sectors
1. Coal Preparation Plants:
● Replaces jigging and heavy medium coal washing for lump coal, directly producing clean coal and reducing production costs.
● In underground coal mines, it can discard gangue from lump coal, allowing direct gangue backfilling and saving hoisting costs.
2. Metal Recovery Industry:
● Enables separation of metals such as aluminum, copper, zinc, and lead.
● Applicable for waste sorting and sorting of automotive recycling shredded materials.
Key Performance Features
1. High Recognition Accuracy:
● First-time use of charge-coupled device delay collection technology significantly improves X-ray transmission material recognition accuracy.
● Adjustable resolution up to 100 µm.
2. Long Sensor and X-ray Generator Life:
● Radiation protection technology using visible light double-sided mirrors and X-ray shielding glass extends the lifespan of X-ray transmission sensors by more than three times, reaching international leading standards.
3. Wide Sorting Particle Size Range:
● Pneumatic blow valve allows sorting of ore sizes over 300 mm.
● Multiple types of nozzles arranged in a matrix provide a broad particle size sorting range.
4. Fast Operation Speed and High Recognition Accuracy:
● Sorting recognition algorithm uses SDSOC architecture for software-hardware collaborative design, offering fast operation speed, high recognition accuracy, and high conveyor belt speed, leading to high single-machine output.
5. High Degree of Automation and Simple Operation:
● Features an automatic learning function, setting detection parameters according to different mineral properties to meet various sorting requirements.
● All operations are conducted on the upper computer with one-click start, ensuring simplicity and ease of use.
By integrating these advanced features, Huate’s XRT series intelligent sorting machines represent a significant advancement in the efficiency and cost-effectiveness of mineral processing within the mining industry.
