Equipment for processing and injecting coal powder for discharging 70-80 mesh

To process and inject coal powder with a particle size of 70-80 mesh, you will need a combination of equipment and techniques to ensure efficient and safe operation. Here is a suggested equipment list for achieving this goal:

1. Coal crusher: A coal crusher is essential for reducing the particle size of coal blocks or chunks. Choose a crusher with a capacity that matches your production requirements. Common types of coal crushers include jaw crushers, hammer mills, and roller crushers.

2. Screening equipment: After crushing the coal, you will need to separate the particles based on their size. Install a suitable screening machine, such as a circular vibrating screen or a linear vibrating screen, with a mesh size that corresponds to your desired 70-80 mesh output.

3. Dryer: Coal powder often contains moisture, which can affect the injection process and lead to equipment damage. A dryer is crucial for removing excess moisture from the coal powder before injection. Fluidized bed dryers or rotary drum dryers are suitable for this purpose.

4. Pulverizer or mill: To ensure a consistent 70-80 mesh particle size, you may need to further grind the coal particles. A pulverizer or mill, such as a ball mill or an impact mill, can be used for this step.

5. Silo or storage bin: A silo or storage bin is necessary for storing the processed coal powder before injection. Choose a bin with a capacity that can accommodate your production volume and ensure proper aeration to prevent dust buildup.

6. Conveying equipment: Install conveying systems, such as belt conveyors or screw conveyors, to transfer the coal powder from the crusher, dryer, and storage bin to the injection point.

7. Dust collection system: Coal powder handling and processing can generate significant dust, which may pose a health hazard and contaminate the workplace. A dust collection system, such as a cyclone separator or a baghouse filter, is essential for maintaining a clean working environment.

8. Injection equipment: Depending on your specific application, choose appropriate injection equipment. Common injection methods include pressure injection, vacuum injection, and fluidized bed injection. Ensure that the injection equipment is compatible with the coal powder's particle size and moisture content.

9. Control system: Install a monitoring and control system to regulate the entire processing and injection process. This system should be capable of adjusting the crusher, dryer, mill, and injection equipment parameters to maintain the desired 70-80 mesh particle size.

10. Safety equipment: Equip the facility with necessary safety gear, such as dust masks, safety goggles, and protective clothing for operators. Install emergency stop buttons and machine guards to prevent accidents and injuries.

By integrating these equipment and techniques, you can efficiently process and inject coal powder with a particle size of 70-80 mesh, ensuring optimal performance and safety in your operations. Regular maintenance and inspection of the equipment are also crucial to maintaining optimal performance and preventing unexpected downtime.
