At present, the domestic market has great demand for large-scale slag vertical mills, especially in the iron and steel industry. More than 10 enterprises such as Baosteel, Anshan Iron and Steel, Shougang, Jinan Iron and Steel have put into operation or are building vertical mill production slag powder production lines. Although many domestic enterprises have started the research and development of large-scale vertical mills by introducing advanced foreign technologies, none of them have realized completely independent intellectual property rights. At present, the most well-known slag vertical mill manufacturers in the world include Loesche, Burlesius in Germany, Smith in Denmark, Ube Industries and Kawasaki Heavy Industries in Japan. But before this, my country's large-scale vertical mill relied on imports for a long time and was expensive, which severely restricted the promotion and application of this technology in my country.
It is reported that the first large-scale slag vertical mill in China has been successfully put into production in Jiangsu. This is my country’s first large-scale slag vertical mill with completely independent intellectual property rights. Its technology has reached the world’s advanced level and has filled the design and production of large-scale vertical mills in my country. The above gap broke the monopoly of foreign products in China's large-scale new dry process cement production line vertical mill technology and equipment.
As far as the current domestic situation is concerned, the prospects are very good, but there are not many manufacturers of vertical mills. The reason is that this large-scale industrial mill has too high requirements for technology research and development, production capacity and service. Many small and medium-sized mill manufacturers are unable to meet the requirements. Heavy Industry has many years of experience in the production and research and development of Raymond mills. Under the leadership of the company’s R&D engineers, they have concentrated on research and development of a new generation of LM vertical mills. This kind of powder mill has good grinding effect and low energy consumption; breakthroughs have been made in the layout of the grinding roller, the roller sleeve, and the thin oil circulation system of the bearing, which improves the work efficiency; the powder separator adopts a dynamic and static powder separator with a rotor to improve Improves the efficiency of powder selection; the control system is easy to operate, superior to similar foreign products.
