Vertical Mill for Efficient Steel Blast Furnace Slag Micro-Powder Processing
We provide a wide range of mills — including Raymond mill, trapezoidal mill, vertical mill, ultrafine mill, and ball mill, obtained ISO9001 international quality certification, EU CE certification, and Customs Union CU-TR certification. Suitable for processing minerals such as limestone, phosphate, quicklime, kaolin, talc, barite, bentonite, calcium carbonate, dolomite, coal, gypsum, clay, carbon black, slag, cement raw materials, cement clinker, and more.
The discharge range of these mills can be adjusted to meet specific processing needs, typically from 80-400 mesh, 600-3250 mesh, and can achieve the finest particle size of up to 6000 mesh(D50).

Revolutionizing Slag Processing with Advanced Vertical Mill Technology
In the metallurgical industry, steel blast furnace slag represents both a challenge and an opportunity. Traditionally considered a waste byproduct, modern grinding technologies now enable its transformation into high-value micro-powders for construction materials, cement additives, and chemical applications. At the heart of this transformation lies vertical mill technology – a solution that combines efficiency, environmental sustainability, and precision particle size control.

The Unique Demands of Slag Micro-Powder Production
Processing blast furnace slag into micro-powders presents several technical challenges:
- High hardness and abrasiveness of slag particles
- Requirement for precise particle size distribution (typically 325-2500 mesh)
- Need for integrated drying of moist slag materials
- Demand for dust-free operation to meet environmental standards
Conventional ball mills often struggle with these requirements, consuming excessive energy while delivering inconsistent product quality. This is where modern vertical mills demonstrate their superiority.
MW Ultrafine Grinding Mill: The Optimal Solution
Our MW Ultrafine Grinding Mill represents a breakthrough in slag micro-powder processing. With an input size capacity of 0-20 mm and throughput ranging from 0.5-25 tph, this system delivers unmatched performance for slag applications:

Key Advantages for Slag Processing:
