Automatic Vertical Slag Grinding Mill

1. Product Overview

High Efficiency Energy Saving Slag Vertical Roller Mill is an integrated drying and grinding equipment specially designed for granulated blast furnace slag and steel slag processing. It produces high-quality S95/S105 GGBS powder with low power consumption, stable operation and large output, widely used in cement admixture, concrete and mineral powder production industries. As a professional Chinese manufacturer, we provide complete customized slag grinding plant EPC solutions for global clients.

2. Core Advantages

Energy-saving – Layered grinding cuts power use by 20–30% vs. ball mills, lowering operating costs.

Integrated drying & grinding – Handles feed moisture up to 15% in one step, eliminating extra dryers and reducing investment.

Precise fineness control – Adjustable GGBS fineness (4200–4500 cm²/g) with uniform particle size for high-grade additive applications.

Durable & low-maintenance – Wear-resistant components ensure long service life, low vibration, noise, and replacement frequency.

Eco-friendly – Fully enclosed negative-pressure operation prevents dust emissions, meeting global environmental standards.

Tailored solutions – Customizable capacities with full EPC support: layout, installation, commissioning, and after-sales service.

4. GGBS Vertical Roller Mill Working Principle:

The motor drives the grinding disc to rotate through a reducer. Material falls from the feed inlet onto the center of the grinding disc, while hot air enters the mill through the air inlet. Under the action of centrifugal force, the material moves toward the edge of the grinding disc. When passing through the annular groove on the grinding disc, it is subjected to intense pressure from the grinding rollers and is thereby pulverized. After pulverization, the material is carried up by the high-speed airflow at the air ring near the edge of the disc. Coarse particles are directly thrown back onto the grinding disc for further grinding. The material entrained in the airflow passes through the dynamic and static classifier, where, under the action of the rotating rotor, coarse particles are returned to the grinding disc for re-grinding, while qualified fine particles are carried out with the airflow and collected in the dust collection device as the final product. During the process, the moisture-containing material is dried through contact with the hot gas, achieving the required product moisture content.

5. Vertical Slag Mill Application Scope

Widely used in steel mill slag recycling, cement raw material processing, commercial slag powder stations, and concrete batching plants. The high-quality GGBS produced effectively replaces cement clinker—reducing costs while enhancing concrete strength and durability, delivering significant economic and environmental benefits.

8. 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.
