In the field of coal mining and processing, the separation of coal blocks and gangue has always been an important technical challenge. Traditional sorting methods often have low efficiency, and there are significant errors and safety hazards in manual operations. With the advancement of technology, the research and application of X-ray detection high-pressure gas injection sorting system for coal gangue provide a new solution to this problem.



The working principle of this system is based on the combination of X-ray detection technology and high-pressure air injection technology. Firstly, rapid and accurate detection of coal blocks and gangue is carried out using X-ray detection equipment. X-rays can penetrate substances and produce different attenuation based on their different components and structures, thereby achieving precise identification of coal blocks and gangue. The detection system compares preset parameters to determine whether the material is coal or gangue, and transmits the results in real-time to the sorting system.

After receiving the detection results, the sorting system quickly responds. For materials identified as coal blocks, the system will continue to maintain their motion trajectory and transport them to the designated collection area; For materials identified as gangue, the system will immediately activate the high-pressure air spraying device to separate the gangue from the material flow through precisely controlled airflow and blow it to the collection area on the other side.

This system has significant advantages. On the one hand, it greatly improves the sorting efficiency and realizes real-time automatic sorting of coal blocks and gangue, greatly reducing the need for manual operation; On the other hand, due to the use of advanced X-ray detection technology, the accuracy of sorting has also been greatly improved, effectively reducing the false selection rate. In addition, the system also has a high level of automation and intelligence, which can be adaptively adjusted according to the actual situation, ensuring the stability and reliability of the sorting process.

The application of X-ray detection coal gangue high-pressure gas injection sorting system not only improves the efficiency and quality of coal processing, but also provides strong technical support for the sustainable development of the coal industry. In the future, with the continuous progress and optimization of technology, it is believed that this system will be widely applied in more fields and contribute more strength to the transformation and upgrading of the coal industry.
