With the rapid development of the steel industry, the emission of steel slag is constantly increasing. 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.

LM vertical mill processing steel slag:
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.

Advantages of LM vertical mill in steel slag powder production:
Based on material properties and customer needs, Liming Heavy Industry recommends using LM vertical mill as the core production equipment for steel slag powder production. The entire production line can achieve high construction standards, reasonable layout, and achieve green and environmental protection effects while ensuring production efficiency. The advantages of LM series slag vertical mill include:
01. Leading technology with low investment costs
It integrates crushing, grinding, drying, powder selection, and conveying, with a compact layout and can be arranged outdoors, greatly reducing investment costs.
02. High grinding efficiency and good product quality
Special roller and disc structure design for high grinding efficiency; The particle size distribution of the finished product is uniform, the quality of the finished powder is good, the flowability is good, and the activity is high.
03. Reliable quality and stable operation
The grinding roller is equipped with a limit device to prevent direct contact between the grinding roller and the grinding disc, resulting in low vibration; Equipped with automatic slag removal function, ensuring safe operation of equipment.
04. Strong drying ability and wide adaptability
Hot air can be used to transport materials, drying materials with a moisture content of up to 15% in the incoming mill and a moisture content of less than 1% in the outgoing mill, with wide adaptability.
05. High degree of automation
By adopting an automatic control system, remote control, chain protection, reliable operation, and simple operation can be achieved.
06. Easy maintenance and low operating costs
The grinding roller adopts forced thin oil lubrication and is equipped with a hydraulic flipping device. During maintenance, the grinding roller can be flipped out of the machine by the hydraulic device without disassembly, which is convenient and fast.
