How to deal with steel slag to achieve resource utilization

28 Sep,2020 UTC+8 Views:



CHAENG is committed to providing solutions for the comprehensive treatment of industrial waste slag. It conducts comprehensive exploration on the comprehensive treatment of steel slag. Aiming at the raw material characteristics of steel slag, it uses vertical mills as the main grinding equipment and proposes a general contract service plan for the comprehensive utilization of steel slag throughout the process. From "waste" to "Golden Mountain", from steel "leftover banquet" to "resource banquet", steel slag deformation will help steel enterprises to realize the resource utilization of steel slag.


1.Raw material transfer system

Auxiliary equipment: slag pot

The slag tank required for the transfer of steel slag raw materials in the steel plant is the leading product of the chaeng large casting base. The chaeng slag pot adopts one-piece casting, which has the advantages of strong resistance to deformation and long service life: up to 6000 times, which is 20% higher than the same industry. It is a high-quality supplier of slag tank products from well-known steel groups such as Mittal and Tata.

2.Pretreatment system

Customized process: At present, the steel slag pretreatment process of domestic iron and steel enterprises includes water quenching, air quenching, hot splashing, thermal braising, aging, etc. There are many processes. There are also roller technology and hot braising technology. Xinxiang Great Wall can recommend scientific solutions for you according to your needs.

3.Crushing magnetic separation system

Auxiliary equipment: Rod mill

The pretreated steel slag is purified and magnetically separated by a rod mill to realize the separation of slag and steel. The iron grade of slag steel above 85% can be directly returned to the converter, and the iron grade of magnetic separation powder above 40% can be returned as sinter ingredients. . The metal iron content in the tailings is less than 2%, which can be used to produce steel slag powder, reducing metal resource waste; the overall production process has low noise and less dust, reducing environmental pollution.

4.CHAENG Grinding System:
Auxiliary equipment: GRMSS series steel slag vertical mill

After crushing and magnetic separation, the steel slag ≤5mm and the metal iron content ≤2% enters the GRMSS series steel slag vertical mill developed by Xinxiang Great Wall for final grinding.

System advantages of Xinxiang Great Wall Machinery Steel Slag Production Line:


1.With independent patents, reliable performance

It has its own patented technology in removing iron before, during and after grinding, which can adapt to the characteristics of poor grindability and high iron content of steel slag, and the equipment runs smoothly.

2.High yield, good quality and more economical

The GRMS steel slag vertical mill adopts unique roller sleeves and liners. The steel slag powder produced is of high fineness. The specific surface area of ​​the finished product can reach 450-500㎡/kg or more. It has good activity and is suitable for cement active mixtures and concrete admixtures. .

3.Advanced technology, better energy saving effect

Using the vertical mill process, the power consumption per ton of steel slag powder system saves 20% compared to the conventional process. At the same time, the entire production line adopts the DCS central control system, which is highly automated and easy to operate.
