Steel slag is one of the common waste slags in steel plants. The resource recycling of steel slag has always been a big problem. Steel slag ultrafine powder is gradually receiving attention, and its application in the cement concrete industry is increasing.
Steel slag is waste slag produced during the steelmaking process. Depending on the steelmaking furnace, it includes converter slag, open hearth slag, electric furnace slag, etc. It can also be divided into acidic slag, alkaline slag and neutral slag according to its properties. After the steel slag comes out of the furnace, after a series of treatments, the large particles of iron lumps are recovered by the steel plant. The remaining steel slag tailings are the raw materials for producing ultra-fine steel slag powder. Steel slag ultrafine powder can be supplied to mixing stations and mixed with ore powder, tailings powder, fly ash, etc. to produce composite mineral powder, which can be used in place of cement clinker. In this way, the amount of clinker can be saved, thereby saving production costs, and solid waste can be consumed in large quantities to achieve resource utilization. Composite ultrafine mineral powder is also a trend in the future market, and steel slag ultrafine powder has broad prospects.
The steel slag ultrafine powder mill is a large-scale grinding equipment for grinding steel slag powder. It can process steel slag ultrafine powder on a large scale, and the final particle size can reach more than 600 ratio. The larger the specific surface area of steel slag powder, the better its stability, which can also avoid the possibility of expansion of concrete products. The GKLM series vertical mill is a high-efficiency and energy-saving steel slag ultra-fine powder mill. A single device has a large processing capacity. The particle size of the finished product can meet the requirements for ultra-fine powder without becoming coarse, ensuring the application effect. In addition, this equipment has integrated powder making, simple process, high dust collection rate and good sealing. It can be built in the open air and can also have drying function, saving comprehensive investment costs.
