To vigorously develop renewable utilization of resources is one of the most important parts now. For secondary utilization of slag, use Hongxing micro powder mill to grind it into an average particle size of 8 microns of GGBS, and it not only can replace the cement in concrete, but also can improve the performance of concrete. Concrete mixed with blast furnace slag powder has good resistance to chlorine, alkali erosion, micro shrinkage resistance, strong cohesive force with rebar and high strength in late time.Sticking to and carrying forward Hongxing culture is to realize a new round strategic target of Hongxing development, and is the fundamental guarantee to make Hongxing built to last and also is the fundamental guarantee of Hongxing realizing all-round development. Hongxing have developed milling equipment in recent years, and the products are exported to Americas, Southeast Asia, Africa and other dozens of countries.Hongxing milling equipment is the industry leader, including high productivity mill, Raymond mill, micro powder mill and other various types. The products are famous for their environmental protection, energy saving, high efficiency and stability. Hongxing has been with good reputation all the time, and has aimed at making the first brand of milling equipment.Hongxing micro powder mill is mainly suitable for superfine grinding of limestone, activated carbon, cement, phosphate rock, gypsum, glass and other non combustible minerals and more than 280 kind materials of architectural material industry; generally speaking, people have also been associated their lifestyles with milling equipments. Much food processing also has an important link -- grinding powder, such as the grinding of wheat, maize and other granular materials, but more is applied in mining. Micro powder mill is the key equipment used after crushing materials, which has model with a cylindrical rotating structure consisting feeding, discharging, rotary department and gear form and has...
