slag vertical roller mill can be designed to requirements

Slag Vertical Roller Mill Overview

Through the highly integrated process design, Slag Vertical Roller Mill is able to complete a number of processing links within the same equipment, and it has a smaller footprint, low investment costs, and the operating costs are also significantly reduced compared with the traditional mill system, which is a kind of grinding equipment that is very suitable for the requirements of modern technology.

Features of Slag Vertical Roller Mill

1. Integrated design: Slag vertical roller mill combines grinding, drying, classification and other processes together, avoiding the use of multiple independent equipment, reducing the footprint and equipment investment.
2. High efficiency and energy saving: The equipment adopts advanced grinding process, high grinding efficiency, low energy consumption, can maintain high productivity while effectively reducing operating costs.
3. Strong drying capacity: Slag material can contain high moisture (8% to 15%) when it is fed into the mill, the vertical mill rapidly dries the material through the internal hot air system, which ensures the stability of the grinding process.
4. Long life and low maintenance cost: Slag vertical roller mill adopts wear-resistant materials and advanced design, long service life, and maintenance work is relatively simple, effectively reducing the downtime.

Advantages of Slag Vertical Roller Mill

1. Low energy consumption, high efficiency: Slag vertical roller mill design of conical grinding rollers and large diameter grinding disc combination, so that the friction between the grinding rollers and the grinding disc is small, low operating resistance of the grinding rollers, so as to achieve lower energy consumption and higher grinding efficiency.
2. High stability: The equipment adopts liquid-gas combination of spring loading system, which can effectively avoid the metal contact between the grinding roller and the grinding disk, ensure the stable operation of the system and extend the service life of the equipment.
3. Strong drying capacity: Slag vertical roller mill is equipped with a hot air furnace inside, which can effectively take away the moisture in the material during the grinding process, ensure the drying effect of the material, and ensure the continuity and stability of production.
4. High quality of grinding: The mill is reasonably designed, thin and uniform layer of grinding material to ensure uniform particle size distribution, reduce the wear and tear of the material, and improve the quality of the finished product.

Working Principle of Slag Vertical Roller Mill

Based on its roller milling technology. Raw slag enters the feeding bin through the grapple machine, and after measured, it is sent to the spiral feeding device of the mill through the conveying belt. The feeding device feeds the material evenly into the grinding disk, and under the action of centrifugal force, the material moves towards the edge of the grinding disk, and after compaction, degassing and pulverization, the material is brought up by the hot air introduced by the wind ring, and is dried instantly. After grinding, the fine granular materials are brought into the powder separator for sorting, and the qualified fine powder enters the bag-type dust collector to collect the finished products. The coarse powder is returned to the mill for regrinding. In order to ensure the stable operation of the equipment, part of the large particles at the wind ring (such as iron slag) through the slag spitting mouth into the external recirculation system, after iron removal treatment and re-entering the mill for grinding.

Application Areas of Slag Vertical Roller Mill

• Cement industry: Slag vertical roller mill is an important equipment for the production of slag cement, which can grind slag efficiently and produce cement powder that meets the standard.
• Metallurgical industry: Slag vertical roller mill is used for smelting slag crushing treatment in the metallurgical industry to help improve the recycling rate of slag.
• Construction materials: Slag powder as a high-quality building material, in the production of concrete, reinforced concrete and other important applications, slag vertical roller mill can provide stable and efficient production of slag powder.
• Environmental protection industry: In the field of environmental protection, slag vertical roller mill can be used for grinding and processing waste slag, promote resource recycling and reduce waste emissions.
• Other industrial applications: In all kinds of grinding ultra-fine mineral powder industry, slag vertical roller mill also has a wide range of applications, such as ceramics, fertilizer and other industries.

With its advantages of high efficiency, energy saving and stability, slag vertical roller mill has become the equipment of modern grinding process, and has shown its great application potential and market value in cement, metallurgy, construction and other industries.
