How to use X-ray Sorting Technology to Separate Coal Gangue
Release time: 2025-05-21
The efficient separation of coal gangue during coal mining and beneficiation has long been a challenge in the industry. Traditional wet separation consumes a large amount of water resources, and its separation accuracy is limited, while manual sorting suffers from low efficiency and high costs. In recent years, the maturity of the Obote X-ray sorting technology and the application of intelligent algorithms have made intelligent dry separators for mining a core piece of equipment in the coal gangue separation field. With high precision, adaptability, and environmental friendliness, these systems provide a new solution for clean coal production.
Principle and Advantages of X-ray Sorting Technology
Efficient Separation
Principle: X-ray sorting technology works by detecting the material’s internal composition and density differences. X-rays penetrate materials differently based on their composition, allowing for the separation of coal from coal gangue. Coal gangue, which typically contains higher ash content and mineral matter, differs significantly from coal in terms of density and mineral composition. Through X-ray imaging, these differences can be accurately identified and separated.
Separation Precision: X-ray sorting technology can achieve precision down to the millimeter level, effectively distinguishing coal from coal gangue, including accurately separating impurities such as sand and dirt in the coal gangue. This precision far exceeds traditional manual sorting or simple mechanical sorting methods.
Technical Advantages
Efficiency: Traditional coal gangue separation methods rely on manual or gravity sorting, which results in lower work efficiency and is heavily dependent on the operator’s experience. X-ray sorting can work continuously 24 hours a day, with fast sorting speed and high efficiency, capable of identifying coal gangue mixtures in the 3-300mm particle size range.
Environmental Friendliness: X-ray sorting technology does not require chemical agents or rely on hydraulic sorting, reducing environmental pollution and aligning with the development trend of green mining. It is especially suitable for arid regions and environmentally controlled scenarios.
High Recovery Rate: X-ray sorting machine can precisely separate coal, reducing the loss of coal content in the gangue, and improving coal recovery rates.
Application Effects
In the coal mining industry, the use of X-ray sorting technology can effectively reduce the content of coal gangue and increase the purity of coal. Especially in coal mines with a high percentage of gangue, using X-ray sorting technology can efficiently separate coal from coal gangue, thereby lowering the ash content in the coal and improving its quality. At the same time, this technology helps reduce the environmental problems caused by coal gangue accumulation, supporting the comprehensive utilization of coal mine resources.
Obote Intelligent Dry Separator: Dual Mode Process Switching
Gangue Removal and Coal Recovery Mode: This mode is suitable for raw coal with a high gangue percentage, prioritizing the removal of gangue and improving the recovery rate of clean coal.
Coal Removal and Gangue Recovery Mode: This mode is used for pre-treatment of high-quality coal layers, maximizing the retention of coal resources and reducing gangue inclusion.
Obote mining dry separation equipment integrates X-ray sorting technology with artificial intelligence, driving the transition of coal separation from experience-driven to data-driven processes. In the future, with the deep integration of technologies like 5G transmission and digital twins, intelligent sorting systems will create a feedback loop for sensing, decision-making, and execution in mining, injecting new energy into the green and intelligent development of the coal industry.
