Slag is steelmaking blast furnace iron refining decarburization, dephosphorization, desulfurization generated waste. Steel slag powder can be used as a cement mixed material, which can save clinker in cement production, achieve high-quality cement target, improve long-term strength, have good performance and compatibility with concrete admixture.

With the advent of various new types of high-efficiency grinding equipment, especially vertical roller mills, the production of steel slag with high efficiency and low consumption has become a reality, which can provide cement and concrete manufacturers with steel powder with appropriate fineness and good activity.

Advantages of using vertical mill for grinding steel slag:

1.Steel slag vertical grinding can stabilize the steel slag;

2. Power consumption than the ball mill system significantly reduced;

3. Vertical mill system for steel slag production, product fineness adjustment is very convenient. According to the needs of the market and customers, the production of different fineness of the product; (steel slag specific surface area of 450~500m2 /㎏ appropriate, this time better activity, energy consumption indicators ideal)

4. Vertical mill grinding system to optimize the iron process also increased the amount of metal selected, improve the overall economic and environmental benefits of the system
