Coal gangue is a byproduct of coal mining, consisting of stones, minerals with high ash content, and other materials that significantly affect the coal quality. Through effective sorting, coal mines can improve coal utilization efficiency and reduce environmental pollution. The Obote Coal Gangue Sorting Machine is an equipment used in coal mining to separate coal from gangue.

Obote Coal Gangue Sorting Methods:

X-ray and Spectral Imaging Sorting

Principle: This method utilizes X-ray transmission imaging technology, combined with visible light visual analysis and multispectral imaging, to capture real-time differences in density, texture, and color between coal and gangue. The X-ray coal gangue sorting machine can penetrate the ore and generate different image signals based on the density and composition differences of the materials, enabling precise identification of coal and gangue.

Advantages: High sorting accuracy, capable of processing complex coal quality and gangue shape variations, with a sorting precision of over 95%. Additionally, this method does not require water or media, preventing the generation of coal slurry and harmful gases.

Intelligent Recognition and Pneumatic Sorting

Principle: High-definition cameras capture images of the ore, and deep learning algorithms are used to locate and classify coal and gangue. Based on the identification results, high-pressure air nozzles are controlled to blow the gangue out of the coal.

Advantages: Fast sorting speed, suitable for running at conveyor speeds of 0.5 to 2 m/s. The AI algorithm optimizes and dynamically adjusts airflow intensity and sorting thresholds to adapt to different working conditions.

Mechanical Vibration and Screening Sorting

Principle: This method uses a sorting plate and bottom plate combination, adjusting the positions of the screening apertures to control the passage of coal gangue with different particle sizes. The sorting plate vibrates horizontally with the drive of a motor, allowing the ore to be sorted during the vibration process.

Advantages: Adjustable sorting specifications, suitable for sorting coal gangue of different sizes. The equipment has a simple structure, easy to operate, and is ideal for small to medium-scale sorting needs.

Selective Crushing and Screening

Principle: Raw coal is first sorted into different sizes using a rotary screening machine, then sent through a selective crushing sorting machine. Using mechanical and pattern recognition technologies, the gangue and coal are separated.

Advantages: Suitable for handling large raw coal pieces, the combination of crushing and screening improves sorting efficiency.

Obote Coal Gangue Sorting Equipment focuses on efficiency and energy savings in its design. It integrates the above sorting methods to achieve higher coal quality purification and gangue recovery efficiency. The combination of these sorting methods maximizes resource utilization, reduces environmental pollution, and promotes the sustainable development of the coal mining industry.
