vertical roller mill with low dust pollution for steel slag

Vertical Roller Mill for Steel Slag Overview

Through advanced design and technology, Vertical Roller Mill for Steel Slag is able to realize ultra-fine grinding of steel slag, and the specific surface area of the product can reach 4500 square centimeters to 5000 square centimeters per gram.

Vertical roller mill for steel slag is a kind of high-efficiency material crushing equipment. Through the innovative vertical roller mill technology, it can complete various functions such as grinding, drying, and grading in one equipment. Compared with the traditional ball mill, the vertical roller mill has higher grinding efficiency and lower power consumption, and its smaller footprint and simplified process flow make it suitable for the reuse of steel slag and other industrial wastes. In the process of steel slag treatment and grinding, it ensures the fineness and quality of the product through precise design and optimized airflow system, and also effectively controls the dust pollution in the production process, which is in line with the modern environmental protection requirements.

Working Principle of Vertical Roller Mill

1. Grinding Disk and Rollers Synergy: The material enters the center of the grinding disc through the feeder, while the hot air enters the inside of the mill from the air inlet. With the rotation of the grinding disk, the material is subjected to centrifugal force, expanding outward along the edge of the disk, and is pressed and milled by the grinding rollers in the annular groove. The crushed material is taken up by the high-speed airflow and passes through the airflow sorting system, and the qualified fine powder is discharged with the airflow and collected as the finished product through the dust collection device. The larger particles are brought back to the mill by the airflow to continue grinding.
2. Drying and Fineness Control: Hot air plays the role of drying to help the moisture in the material evaporate quickly, suitable for materials with high moisture content. The fine adjustment of the powder selector ensures that the coarseness and fineness of the materials out of the mill can reach different product requirements. The whole system ensures the grinding efficiency and product quality through precise airflow adjustment and material flow optimization.

Features of Vertical Roller Mill

1. High-efficiency grinding: The grinding efficiency of vertical roller mill is significantly higher than that of traditional mill equipment, which can effectively improve the output and reduce the production time.
2. Strong drying capacity: Through the hot air system, it can complete the drying and grinding tasks at the same time, which is suitable for handling materials with high humidity.
3. Significant energy saving effect: Compared with the traditional ball milling system, the power consumption of the system is reduced by about 20%, which greatly reduces the operating cost.
4. Low noise, low dust: Vertical roller mill adopts sealed design, which can effectively reduce dust leakage and noise pollution, in line with environmental protection requirements.
5. Adjustable fineness: By adjusting the working status of the powder selector, it can meet different fineness requirements and adapt to various product requirements.
6. Strong durability: The equipment is made of high-quality materials, with strong anti-wear performance and long service life.

Advantages of Vertical Roller Mill

1. Reduce operating costs: Efficient grinding technology and reasonable process design significantly reduce operating costs compared with traditional equipment.
2. Significant energy saving: The system’s power consumption is 20% lower than the traditional mill, and does not require a large amount of power consumption for material transfer and heating.
3. Good environmental protection: Equipment sealing is strong, less dust pollution, can greatly reduce the dust and the impact on the environment.
4. High iron selection rate: The equipment has a strong iron selection ability, can improve the economic efficiency of steel slag treatment, reduce the mixing of useless metal.
5. Improve wear durability: Advanced slag discharge belt design effectively reduces the wear of grinding rollers, reducing the maintenance cost of the equipment.
6. Flexible product fineness control: The fineness of the discharged material can be adjusted according to different process requirements to ensure stable product quality.

Application Areas of Vertical Roller Mill

• Iron and steel smelting industry: Steel slag vertical roller mill is mainly used for the grinding of steel slag in the process of iron and steel smelting, which can be ground into products with high fineness and used as additives for cement production and other building materials.
• Construction material production: Through grinding steel slag, it can be transformed into construction materials with market value, which are widely used in cement, concrete and other industries.
• Environmental protection field: Steel slag as a kind of industrial waste, after the treatment of vertical roller mill, can realize the resource utilization and reduce the pollution of waste to the environment.
• Cement industry: Steel slag powder can be used as a mixing material for cement, which can not only improve the performance of cement, but also realize the rational use of resources.
• Metallurgical industry: In addition to steel slag, vertical roller mill is also suitable for grinding other metallurgical wastes, such as slag, bauxite, etc., which can be used for metallurgical by-products recycling treatment.
