◎ Using a fully dry separation technology, coal and gangue can be accurately separated without water. The separation accuracy exceeds that of water washing (jigging) and can operate stably for a long time.
◎ This equipment uses X-ray sensing technology to identify differences in material composition, effectively solving the problems of high water consumption and environmental pollution in traditional water washing processes. It is suitable for coal washing scenarios in arid and water-scarce areas or with high environmental protection requirements, providing a new solution for the clean and efficient utilization of coal.
The XRT separator transports a mixture of coal and gangue via a conveyor belt, while an X-ray source emits rays that penetrate the material. Coal and gangue exhibit significantly different absorption and attenuation characteristics for X-rays. A dual-energy receiver collects the penetrating X-ray signals, which are then analyzed by an AI algorithm to accurately identify the differences between the two materials. When the target material reaches the sorting area, a pulse-jet system separates the gangue and coal. Depending on the ore properties, visible light or infrared cameras can be added for composite identification, further improving sorting accuracy.
◎ Core components are original products from internationally renowned brands, ensuring high reliability and long lifespan.
◎ Utilizes advanced algorithms in collaboration with RWTH Aachen University in Germany, resulting in fast processing speed and high accuracy.
◎ User-friendly interface; sorting parameters can be flexibly adjusted according to sorting requirements, making operation simple.
◎ The equipment can be centrally controlled, achieving a high degree of automation.
◎ Material conveying speed can reach 3.5m/s, providing a large processing capacity.
◎ Equipped with a built-in uniform material distribution device, effectively preventing mis-blowing caused by material accumulation.
◎ Applications in the coal industry
Combined with descaling and washing processes, it can achieve the separation of 300-6mm thermal coal.
It replaces jigging or heavy media coal preparation to achieve dry separation of 300-25mm lump coal.
◎ Coal recovery from gangue
Suitable for the separation of coal and lignite in water-scarce areas. Also suitable for the separation of other non-coal minerals (such as kaolinite).
