Grinding performance of steel slag vertical mill
Xinxiang Great WallMachineryGRMSSSteel slag vertical mill with product specific surface area reachesAt 4500 cm²/g, the average powder grinding capacity of each steel slag mill is guaranteed at 90t/h. If ball mills are chosen, at least 6 sets of ball mill systems are required. And Xinxiang Great WallMechanicalSteel slag vertical mill utilizes a large amount of external circulation and effectively removes iron from it, enabling the tailings to contain~1.5% iron content removed, the steel slag powder produced has a high fineness, and the specific surface area of the finished product can reach above 450~500 m²/kg, with good activity, suitable for use as cement active admixture and concrete additive, etc.
Product Advantages
1. Vertical mill system has an energy consumption ratio 20% lower than ball mill.
The ball mill system has an excessive energy consumption.It's a major challenge.And the new type vertical mill equipment has become a nationalInterior and exteriorA recognized energy-saving and environmentally friendly powder grinding equipment; compared to ball mill systems, it can save electricity.30~50%. Xinxiang Great WallMechanicalThe steel slag vertical mill has a larger external circulation ratio compared to the traditional vertical mill, which can reduce the system's electrical consumption.Approximately 20%.
2. Low dust pollution, minimal dust emission
We understand that ball mills, due to their complex system processes, require multiple equipment and conveyors, which can result in severe dust pollution. In contrast, the steel slag vertical grinding system integrates conveying, powder grinding, drying, and powder selection into one unit, featuring a full-sealed design. Meanwhile, Xinxiang Great WallMechanicalThe vibration screen frame and the feed house frame are also equipped with dust collectors.Excellent environmental performance。
3. High iron selection rate, enhancing economic benefits
Steel slag typically contains:Iron content ranging from 1% to 3%, Xinxiang Great Wall optimizes the iron selection process for its grinding powder system. By adding multiple iron separators to the feeding system, the quantity of metal iron extracted is significantly increased, enhancing the overall economic and environmental benefits of the system.
4、AdvancedDewatering belt, reduces roller wear
The slag belt utilizes an advanced flat belt and铺设装置 technology, enabling the suspended magnetic separator on the belt to more effectively magnetically separate the ferrous materials discharged from the mill, preventing them from re-entering and reducing wear on the mill rolls.
