Iron and steel industry is the pillar industry of the national economy of a country, also is one of the largest industrial solid waste emissions. Slag is the solid waste emissions in the steelmaking process A is to the metal charge after each element is produced by oxidation oxide, erosion of lining material and fettling materials, metal charge into the impurities, and for the adjustment of slag nature and deliberately added slagging materials such as: limestone, dolomite, iron ore, silica and the like.
Steel slag emissions are about 15% to 20% of steel production, China's accumulation of slag has more than one hundred million tons, and the annual 20 million tons of slag volume increase. Compared with the amount of slag terror, our utilization of slag is lower, and the overall level of utilization is not high. Without effective treatment and resource utilization, slag, take up more arable land, destruction of the ecological balance, environmental pollution, waste of resources, affect the sustainable development of the steel industry. Rational and effective use of steel slag recycling is one important sign of progress in modern steel industrial technology, iron and steel enterprises to solve the shortage of scrap, reduce production costs, improve economic efficiency is an important initiative, but also protect the environment, reduce pollution, harm into turning waste into treasure, the country's good policy. Therefore, reduction, recycling and utilization of high-value steel slag has become an important research topic at home and abroad.
Shanghai Clirik produced series vertical mill machine with a reasonable and reliable structural design, with advanced technological process, set the crushing, drying, grinding, separator, delivery in one, especially in the steel slag grinding process, with unique advantage. Shanghai Clirik vertical mill use material layer grinding slag, low cost energy consumption, high production efficiency. Slag vertical mill inside the residence time is only 2 to 3 minutes, a ball mill residence time of 1/10 to 1/5, it can be quickly measured, chemical composition and fineness of the correction slag, stable quality, particle size distribution uniform. Also vertical mill fully sealed system; the system operates under negative pressure, no dust, in line with national environmental standards.
According to company's existing milling equipment, vertical mill can be taken, the European version coarse vertical grinding mill, Raymond vertical mill, etc. finish grinding process, or to use a ladder + ultrafine grinding mill, Raymond mill + micro-grinding  mill and other joint powder grinding process. According to the company can slag or slag emissions guarantee supply, as well as local and neighboring markets in demand for steel slag fine powder, determine reasonable production technology and scale.
