HVM Slag (Steel Slag) Micro Powder Vertical Mill Specifications & Technical Parameters Table

Working Principle of Vertical Mill

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.

FAQ

1. What materials can your slag vertical mill grind?

Our vertical mill is specially designed for blast furnace slag grinding, and is also suitable for other similar industrial solid wastes: steel slag, fly ash, coal gangue and other materials with similar grindability and processing requirements.

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

The processing capacity for slag is 3–200 tons per hour.

The fineness of finished slag powder / GGBS can be adjusted between 200 mesh and 1250 mesh according to application requirements in cement, concrete and building materials industries.

3. How to choose the right model for my slag processing project?

We need to know: raw slag type (blast furnace slag / steel slag), required capacity (tons per hour), finished product fineness (mesh), moisture content of raw material, application scenario (cement, concrete, GGBS production) and site conditions.

Our engineers will recommend the most suitable model for you.

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

For slag grinding, the vertical mill has obvious advantages:

higher efficiency (increased by 30%–50%), lower energy consumption, larger capacity, smaller footprint, more environmentally friendly (less dust and noise), and easier maintenance. It is more suitable for large-scale slag powder and GGBS production than ball mills.

5. Can you provide customized slag vertical mills?

Yes. We can provide customized design and production according to your slag processing requirements, including capacity, fineness, site layout, voltage and special working conditions (such as high-moisture slag).

6. Do you provide a complete slag powder production line?

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

7. How about the installation and after-sales service of the slag vertical mill?

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

8. What is the delivery time of the slag vertical mill?

Customized production line: about 90–120 working days.

The exact delivery time will be provided after confirming the model and specific requirements.

9. What control system does the slag vertical mill adopt?

It adopts an advanced PLC automatic control system, realizing intelligent control of slag feeding, grinding, classification and drying. It supports remote monitoring and fault alarm, and is easy to operate.

10. Does your slag vertical mill meet international standards?

Yes, our products comply with international industrial standards and have relevant certifications such as CE and ISO, ensuring quality, safety and environmental protection requirements, and can be exported to global markets.
