Granulated blast furnace slag (abbreviated as slag) is an industrial waste discharged during the smelting of pig iron in blast furnaces. Due to its high physical and chemical activity and potential hydraulic hardening, it is widely used as a admixture in China's cement industry. The slag micro powder grinding system utilizes industrial waste residue from the metallurgical industry, which not only turns waste into treasure, increases the added value of slag, and creates considerable economic benefits for steel enterprises, but also saves a large amount of non renewable resources, in line with the policies of structural adjustment in the steel and cement industries.

　　Driven by the vigorous development of circular economy, a new wave of waste utilization is emerging, and slag powder will be widely used in high-performance and high-strength concrete. Slag powder can replace a large amount of cement in concrete, significantly improving the workability of fresh concrete and the durability of hardened concrete, with significant later strength. Concrete prepared with slag powder can be widely used in various construction projects, bringing good economic benefits to concrete production enterprises and playing an immeasurable role in resource conservation, comprehensive utilization, and environmental protection.

　　After years of technological accumulation and combined with on-site user experience, Jiangsu Pengfei Group continuously improves and perfects its Pengfei brand slag vertical grinding ultrafine powder production line, which is reliable in quality, energy-saving, and has obvious benefits. It has been unanimously recognized by a large number of users and has become a landmark product in the new technology field of slag ultrafine grinding. This equipment has the advantages of high grinding efficiency, large drying capacity, easy adjustment of product fineness, low noise, low power consumption, simple process flow, low wear, and low operating costs.
