Vertical Grinding System Process
Raw materials are elevated into a silo, then fed into a vertical roller mill for grinding and drying. Qualified fine powder is separated via a classifier and cyclone, while coarse powder returns for regrinding. Exhaust gas is purified by a bag filter before emission. Finished powder is stored in a silo, ready for packaging or dispatch.

FAQ – Slag Vertical Mill Grinding System
1. What materials can your slag vertical mill system process?
Our system is specially designed for grinding metallurgical wastes, suitable for various types of slag and industrial by-products, including granulated blast furnace slag, steel slag, nickel slag, manganese slag, and other materials with similar grindability.
2. What capacity and fineness can your system achieve?
For slag micro powder processing, the system capacity ranges from 15 to 150 tons per hour (or an annual output of 100,000 to 1,000,000 tons). The finished slag powder fineness can be adjusted between 400–550 m²/kg (specific surface area) to meet S95 grade and above standards for cement and concrete applications.
3. How do I choose the right system model?
Our engineers will recommend the most suitable model based on your raw material type (blast furnace slag, steel slag, etc.), required capacity, target fineness, raw material moisture content, application scenario (cement plant, concrete batching station, etc.), and site conditions.
4. What is the difference between a vertical mill and a ball mill for slag grinding?
Compared with a ball mill, our vertical mill offers higher grinding efficiency (20%–30% increase), lower energy consumption (30%–50% reduction), larger capacity, smaller footprint, better environmental performance (less dust and noise), and easier maintenance—making it the ideal choice for modern slag micro powder production lines.
5. Can you provide customized slag grinding solutions?
Yes, we provide customized design and manufacturing based on your specific requirements, including capacity, fineness, material type, site layout, and special conditions such as high-moisture slag.
6. Do you offer a complete slag micro powder production line?
Yes, we provide turnkey solutions covering the entire slag grinding process, including crusher, bucket elevator, feeder, vertical mill, dust collector, control system, and product storage or packaging equipment.
7. What installation and after-sales services do you provide?
We offer on-site guidance for installation and commissioning, operator training, long-term supply of wear-resistant spare parts, and 24/7 online technical support to ensure stable operation.
8. What is the delivery time?
Delivery time is approximately 90–120 working days for standard models, and around 120 working days for customized production lines.
9. What control system does your slag grinding system use?
The system is equipped with an advanced PLC automatic control system with a touch screen interface, enabling intelligent and unmanned operation of feeding, grinding, classifying, and drying, with remote monitoring and fault alarm functions.
