Weigang uses a single slag mill to grind new slag and clinker separately

Xi'an University of Architecture and Technology Powder Research Institute undertakes the design of Sichuan Weiyuan Iron and Steel Co., Ltd. to produce 1 million tons of slag cement production line annually. In China, it uses a single slag vertical mill for grinding slag and clinker for the first time, and then stirs and mixes to produce slag cement. Process, which will have a major impact on the promotion and application of new slag cement technology in China.
Blast furnace water quenching (slag) is a by-product of ironmaking production. According to relevant statistical data, the national pig iron production in 2002 was 170 million tons, and the calculation of 0.65 tons of slag with a domestic average production of 1 ton of pig iron produced 105 million tons of slag. More than 50% of slag in China is used as a blended material for cement production. Today, admixtures of slag fines have become different from the usual fineness of the past. As the powder particles are sufficiently refined, their surface properties are significantly increased, and the resulting surface effects impart new properties to the concrete mix while also improving the strength and durability of the concrete. Therefore, domestic researchers have focused on the development and application of ground slag admixtures in recent years. Research and development of high-performance concrete has also become a hot topic in the international arena.
Xi'an University of Architecture and Technology Powder Engineering Research Institute was established in 1986. It is a new science and education entity integrating scientific research, teaching, postgraduate training, engineering design and consulting, new technology development, and patented product processing. The institute started its research work on concrete since the 1990s, and focused on the application of industrial waste (steel slag, slag, and fly ash) in cement and concrete. Its achievements won the first prize for regional scientific and technological progress and passed. Provincial technical appraisal. It is reported that Sichuan Weiyuan Iron and Steel Company and Taiyuan Iron and Steel Company's annual output of 1 million tons of slag production line design work has basically been completed and is expected to be completed and put into production in February 2004.
