The Slag Vertical Roller Mill (VRM) is a high-efficiency, energy-saving grinding equipment specifically designed for processing blast furnace slag into GGBFS (Ground Granulated Blast Furnace Slag) — a high-value additive for cement and concrete production.Integrating drying, grinding, classifying, and conveying into a single compact unit, our vertical mill delivers superior performance with 30–50% lower power consumption compared to traditional ball mills, while producing slag powder with consistent fineness up to 420–600 m²/kg (Blaine) .

Whether you are building a new GGBFS production line or upgrading an existing plant, our slag vertical roller mill offers the ideal balance of capacity, reliability, and low operating costs.

Core advantages of the product

Advantage 1	Advantage 2	Advantage 3
Energy Saving: 30–50% Power Reduction	Wear-resistant Construction	Easy Maintenance
The vertical grinding process saves 30–50% power compared with conventional ball mills, with unit power consumption of only 40–50 kWh per ton, greatly cutting operational costs.	The grinding rollers and liners are made of high-chromium wear-resistant alloy, featuring long service life and fewer shutdown replacements.	Grinding rollers can be swung out of the mill housing for maintenance; the hydraulic loading system features convenient adjustment to boost maintenance efficiency.
Adjustable Fineness	Multi-functional for Various Materials	Low Noise & Eco-friendly
Fitted with built-in high-efficiency dynamic classifier, the specific surface area of finished GGBFS is adjustable from 420 to 600 m²/kg to meet diverse customer requirements.	It integrates drying, grinding, classification and conveying in one unit, capable of processing slag, steel slag, fly ash and other raw materials simultaneously.	The system operates under negative pressure, with dust emission below national standards and noise controlled under 85 dB.

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.

Our Slag Vertical Roller Mill is widely used in:

GGBFS Production Lines – producing ground granulated blast furnace slag powder for cement and concrete admixtures .
Cement Plants – as a standalone slag grinding station or integrated with clinker grinding systems .
Steel & Metallurgical Industry – processing steel slag and other industrial by-products into value-added micro-powders .
Mining & Mineral Processing – grinding various ores and industrial minerals with medium hardness

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.
