What kind of grinding mill is used for processing steel slag?

With the rapid development of the steel industry, the emission of steel slag is constantly increasing. Data shows that the annual emission of steel slag is about 19 million tons, accounting for 10% -15% of steel production. Due to its similar chemical and mineral composition to Portland cement clinker, steel slag has considerable chemical activity.

At present, vertical grinding technology is used to grind steel slag micro powder and produce products that replace high-energy consumption cement clinker. It is widely used in industrial and civil construction, water conservancy, road and airport construction projects, and belongs to the advanced production process in the industry. It has the characteristics of advanced technology, stable and reliable, excellent particle size, energy conservation and environmental protection. The high-value utilization of steel slag not only effectively alleviates the problems caused by steel slag storage, protects the environment, turns waste into treasure, but also improves certain characteristics of cement, reduces costs and increases efficiency, saves energy and resources, and plays a positive role in building a "waste free city" and promoting the sustainable development of the steel industry.

If the LM vertical mill produced by Liming Heavy Industry is used to process steel slag, the production process is as follows: raw materials such as steel slag are transported into the factory by loading trucks, and then sent to the steel slag storage shed for storage through unloading hoppers and belt conveyors. The stacked steel slag is picked up by a forklift and sent to the receiving hopper. It is then sent to the elevator through a quantitative feeding equipment and a belt conveyor. During the conveying process, the steel slag raw materials are first removed by an iron remover, and then sent to the LM vertical roller mill for grinding through locking feeding equipment such as a screw conveyor. The ground steel slag powder is selected by a powder selection machine using the hot air provided by the hot air furnace, and is dried at the same time. The steel slag powder that meets the fineness requirements is collected through a dust collector, and then stored in the finished product warehouse through an air conveying chute and elevator..
