Our steel slag micro-powder production line is a response to the energy conservation and environmental protection policy.Based on the hardness and other characteristics of steel slag, a production line for the recycling and reuse of steel slag and other resources is developed through reasonable equipment configuration. Xinxiang Great Wall undertakesAnnual production capacity of 20-150万吨 steel slag micro-powder production lineEPC Turnkey Project, also offering a "turnkey" service ranging from civil construction to commissioning and production, allowing clients to conveniently, effortlessly, and efficiently invest in steel powder production.
The slag vertical mill, as the main equipment in the slag production line, integrates conveying, powder grinding, drying, and selection into one unit, operating under a fully enclosed negative pressure system. It also equips monitoring devices at dust collection points such as the vibration sieve frame and feed tower frame. The dust emission concentration of the entire line is around 22mg/m³, significantly lower than the standard of 30mg/m³.
The steel slag powder produced by the Xiangxin Great Wall Grinding System should have a specific surface area of 450-500 m²/kg for optimal performance, at which point it exhibits good activity and ideal energy consumption indicators. Advantages:
1. High energy consumption in ball mill systems poses a significant challenge, but vertical mill equipment has been widely recognized as an energy-saving and environmentally friendly grinding solution, capable of reducing individual machine energy consumption by over 30%!
2. Generally, there is an iron content of 1%-3% in steel slag. Xinxiang Great Wall has optimized the iron separation process for the roller mill system, adding multiple iron separators to the feeding system, significantly increasing the amount of metallic iron recovered and enhancing the overall economic and environmental benefits of the system.
3. Xinxiang Great Wall has large-scale machining capabilities and large cast steel production capacity. It can ensure a delivery period of 4-6 months for steel slag vertical mills while maintaining product quality, and can shorten the construction period of the entire production line to 6-8 months.
Application of steel slag micro-powder
Steel slag has a chemical composition similar to cement clinker and becomes active after certain processing. The finely ground steel slag can be mixed with the required gypsum and admixtures in cement, then processed in a ball mill to produce slag cement. Concrete made with slag cement boasts excellent physical and mechanical properties, such as high later strength, good frost resistance, stability, and more. When the steel slag content in concrete is appropriate, the durability of the concrete can be improved to some extent. Coarse steel slag can also be used as aggregate in concrete. After aging treatment, steel slag can be used to produce bricks, paving bricks, curbs, slope protection bricks, blocks, and other products.
In addition, steel slag features good particle gradation and hardness, with stable performance and high compressive strength, making it suitable as backfill material for road construction projects.
Thus, the utilization scope of steel slag is relatively broad, which also reflects a significant room for improvement in the technical aspects of consulting and processing steel slag. The effective and rational use of steel slag can play a role in protecting the environment, enhancing economic benefits, and promoting the sustainable development of resources, holding great significance for society.
