High Output Vertical Coal Grinding Mill

Working Principle

1. The motor drives the grinding disc to rotate via the reducer. Meanwhile, material falls from the feeding port to the center of the rotating grinding disc, and hot air enters the grinding chamber through the air inlet.

2. Under the action of centrifugal force, the material moves to the edge of the grinding disc. When it passes through the circular groove on the disc, it is crushed by the grinding roller.

3. The crushed material is picked up by the high-speed airflow at the edge of the grinding disc. Large particles directly fall back onto the disc for re-grinding.

4. The material carried by the airflow then passes through the dynamic-static separator. Under the action of the rotating rotor, coarse powder falls back to the grinding disc for re-grinding, while qualified fine powder is carried by the airflow.

5. The qualified fine powder is collected by the collecting device and becomes the final product.

6. For materials containing moisture, they are dried during contact with the hot air, ensuring the final product meets the required moisture content.

Vertical Coal Mill Applications

Steel Mills & Blast Furnaces: Preparing PCI (Pulverized Coal Injection) fuel.

Thermal Power Plants: Producing high-fineness coal for efficient boiler combustion.

Chemical Industry: Supplying uniform pulverized coal for gasification and chemical synthesis.

FAQ

1. What materials can your vertical mill grind?​

Our vertical mill is specially designed for coal grinding, and is also suitable for grinding various coal-based materials and related fuels, such as bituminous coal, anthracite, lignite, coal gangue, coal slime, and other materials with similar grindability to coal.​

2. What is the capacity and fineness of your vertical mill?​

For coal powder processing, the capacity ranges from 3 to 200 tons per hour, and finished coal powder fineness can be adjusted between 200 mesh and 1250 mesh according to customer’s application requirements (such as power plants, cement plants, boilers).​

3. How to choose the right model?​

We need to know your raw coal type (bituminous coal/anthracite/lignite), required capacity, finished coal powder fineness, moisture content of raw coal, application scenario (power generation, cement production, boiler combustion) and site conditions. Our engineers will recommend the most suitable model.​

4. What is the difference between vertical mill and ball mill?​

For coal grinding, the vertical mill features higher efficiency (increased by 30%–50%), lower energy consumption, larger capacity, smaller footprint, more environmental protection (less dust and noise), and easier maintenance than ball mill, which is more suitable for large-scale coal powder production.​

5. Can you provide customized vertical mill?​

Yes, we provide customized design and production according to customer’s coal processing requirements, including capacity, coal powder fineness, raw coal type, site layout and special working conditions (such as high-moisture coal slime).​

6. Do you provide complete production line?​

Yes, we provide turnkey coal powder production line including crusher for coal pre-crushing, bucket elevator, feeder, coal powder vertical mill, dust collector, control system and packaging machine, covering the whole process of coal grinding and powder making.​

7. How about installation and after-sales service?​

We provide on-site guidance for installation, debugging, operator training (coal grinding operation and maintenance), long-term supply of wear-resistant spare parts suitable for coal grinding, and 24-hour online technical support to ensure stable operation of the production line.​

8. What is the delivery time?​

For standard coal powder vertical mill models, delivery time is about 90-120  working days. For customized coal powder production line, it is about 120 working days.​

9. What control system does the vertical mill use?​

It adopts advanced PLC automatic control system with touch screen, realizing intelligent and unmanned operation of coal feeding, grinding, classification and drying, and supporting remote monitoring and fault alarm.​

10. Do you have certification?​

Yes, our coal powder vertical mill meets international industrial standards and has relevant certifications such as CE and ISO, ensuring quality, safety and environmental protection requirements, and can be exported to global markets.​
