What is the introduction to steel slag vertical grinding technology?

The historical accumulation of steel slag is large, occupying land resources and causing environmental pollution. Calculated based on 13% of crude steel production,annual steel slag production reaches 135 million tons. How to make full use of steel slag has been a topic worthy of study in recent years. As a steel slag vertical mill manufacturer,Guikuang Machinery will introduce the steel slag vertical mill technology, which has certain promotion value.

Steel slag vertical mill technology is the main production link for comprehensive utilization of steel slag. The steel slag undergoes multiple processes such as hot stewing slag/drum cracking, screening, crushing, magnetic separation, and grinding to select products such as Grade A steel slag, Grade B slag steel, particle steel, mixed slag powder, and concentrate powder. Returning to the steel plant, the tailings pass through the steel slag micron powder production line to produce micron powder, which can be used as raw materials for building materials or to make high-performance soil solidifying agents. The steel slag powder produced by steel slag vertical mill technology can be used in building materials products, not only as cement admixtures, but also as mineral admixtures in concrete. Judging from the proportion of steel slag powder used in concrete, steel slag powder in general concrete can replace 10% of cement, which has certain promotion value. This technology can obtain the required grinding fineness by adjusting the speed of the powder separator, the air flow rate of the mill and the grinding pressure, and combining it with a retaining ring of appropriate height. This equipment integrates crushing, grinding, drying, and powder selection. It has the characteristics of low power consumption, good sealing performance, small footprint, and simple process. The equipment adopts a new vertical mill grinding zone structure, which can realize high-pressure and less-grinding technology for grinding steel slag; it also develops system iron removal and in-mill iron removal to reduce iron enrichment.

Technical functional characteristics of steel slag vertical mill:

(1) The product fineness can be adjusted flexibly, and the material variety can be adjusted as needed.

(2) Low failure rate and strong reliability.

(3) The finished ultrafine steel slag powder can be added to concrete or cement as an active mixing material to replace clinker.

Steel slag vertical mill technology can realize the resource utilization of steel slag tailings and reduce the iron content in the tailings to less than 3%. This technology has high grinding efficiency, good iron removal effect, low system resistance, energy saving effect, and good social benefits and economic value.
