Great Wall Machinery takes the “ one stop service, one window external” as our service principle. We provide the successful solving projects to steel plants, helping them improve the usage of steel slag and improving their benefits.

Now the Chinese steel plant all are facing the problems below:

1. Mineral, water and coal etc are becoming more and more shortage, With the cost rising, their benefits are reducing.

2. The wasted steel slags cause resources wasting.

3. Steel slag occupies large area, also cause deeply environment pollution.

Now our government has put the comprehensive utilization of solid waste as a long term strategy of economic and society development. In the “Tenth five years plan” and “Eleventh five years plan” of the government energy saving and resource comprehensive usage, they all have clearly put forward the goal of industry waste comprehensive usage. In this way, promoting the harmonious developing of economic, resource and environment.

Under this new situation, steel industry has put forward new demands to equipment and production line.

1. Developing the production process, saving the resource and developing the secondary resource reasonably.

2. Improving the resource usage rate, turn waste into wealth.

3. Improving the production process and equipment, reducing the dust pollution.

Customers’ benefits

1. Recover the investment costs in 3 years.

2. Reduce the power consumption significantly with scientific process control and optimization.

3. Reduce the project period and time cost with EPC turn key project.

Project features:

1. Compared with Ball mill, the vertical roller mill can saving power consumption 20%~30%.

2. The vertical roller mill’s noise control meets the Industrial enterprises noise discharging standards (GB12348-2008)

3. Low dust concentration.

4. Highly material drying ability, the final products’ moisture is 0.5~1.0%.

5. Little wear and lower the metal wastage of each unit

6. Specific surface area of slag powder is 4200~4500cm²/g.

7. The occupied area of vertical roller mill is only 50% of ball mill, and reduce the investment directly.
