Energy Saving Limestone Vertical Roller Mill

HVM type high-fine vertical grinding specifications, technical parameter table (electric desulfurization)

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 limestone vertical mill grind?

Our vertical mill is specially designed for limestone grinding, and is also suitable for other non-metallic minerals with similar grindability: calcite, dolomite, heavy calcium carbonate (HCC), etc., which have the same hardness and processing requirements as limestone.

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

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

The fineness of finished limestone powder can be adjusted between 200 mesh (for cement raw material) and 1250 mesh (for desulfurization and denitrification) according to application requirements.

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

We need to know: limestone type (natural limestone/calcite), required capacity (tons per hour), finished product fineness (mesh), moisture content of raw material, application scenario (desulfurization/cement/building materials) and site conditions.

Our engineers will recommend the most suitable model for you.

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

For limestone 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 limestone powder production than ball mills.

5. Can you provide customized limestone vertical mills?

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

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

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

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

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

8. What is the delivery time of the limestone 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 limestone vertical mill adopt?

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

10. Does your limestone 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.
