Coal Processing

TDS^®

As a leading intelligent dry sorting solution for lump coal, MeiTeng TDS^® combines X-ray sensing, imaging recongition, AI algorithms, and precision air-jet technology to deliver efficient, water-free coal beneficiation with exceptional reliability.

How It Works

The MeiTeng TDS^® Intelligent Dry Sortors been launched in 2015, which is based on X-ray and image recognition.The TDS^® system operates through a precise and fully integrated process that combines stable feeding, high-resolution detection, and intelligent sorting execution,as well as the auxiliary system.

1. Feeding and Material Stabilization

Raw coal is fed by a vibrating feeder and spread as a thin, even layer onto a fast-moving conveyor belt. This stable material flow ensures that each particle is clearly exposed and ready for qualitative analysis, providing a condition for accurate sorting.

2. Identification and Analysis

As material passes through the detection area, it is scanned by an X-ray transmission system and CCD imaging. Each particle’s density, composition, and thickness are captured in real time. MeiTeng proprietary big-data algorithms then classify clean coal and waste by generating an intelligent recognition model, ensuring high sorting accuracy.

3. Intelligent Sorting Execution

Analysis results are transmitted to the compress-air execution system. Using precise, energy-efficient solenoid valves, the system can reject waste from valuable clean coal and middlings. Upon operational needs, TDS^® can perform de-stoning, achieve three-stage sorting (clean coal, middlings, waste), or produce direct-shippable product.

4. Auxiliary System Integration

Auxiliary systems of TDS^® include compress-air supply, dust management, power distribution, and centralized control. These systems maintain a clean working condition, reliable power, and highly automated operation, ensuring a long-term stability and efficiency of TDS^® system.

About H Series TDS^®

MeiTeng developed three-products and underground TDS^® models following the first standard TDS^® was successfully applied in 2016. Through years of technology iteration, MeiTeng has recently announced H-type TDS^®. MeiTeng R&D team gave a comprehensive upgrade for H-type TDS^® in sorting accuracy, processing capacity, feed particle size and equipment structure, making a new benchmark in the field of intelligent dry sorting.

Applications

MeiTeng’s TDS^® intelligent dry sorting system offers a versatile solution for modern coal preparation, addressing multiple application needs with efficiency and sustainability:

Coking Coal Sorting

Ideal for mines with high reject content and high transportation costs, or coking coal preparation plants where slime issue increase washing costs. TDS® is able to de-stone efficiently, improving feed quality of wet processing system while significantly lowering downstream processing burdens. De-stoning on the mine site can reduce waste from the source, cut transportation costs, and minimize downstream processing capacity.
