ODM Vertical Raw Mill Roller In Coal Cement Grinding Plant

Energy-saving Consumption-reducing Vertical Roller Raw Mill In Cement Plant

【Application Materials】
Vertical mill is a kind of high-efficiency grinding introduced by the country's continuous increase in R&D investment in machinery manufacturing industry, changes in industrial policies and expansion of production scale in recent years. equipment.

And gradually accepted by the domestic cement, electric power, chemical industry, become the industry's more advanced grinding equipment. It integrates crushing, drying, grinding, grading and conveying, and has high production efficiency. It can grind block, granular and powdery raw materials into required powdery materials. Widely used in cement, electric power, metallurgy, chemical industry, non-metallic minerals and other industries.

【Technical Advantages】

1. The vertical mill adopts material layer rolling, friction and impact as the crushing mechanism, which has the advantages of high efficiency, large energy saving (20-30% energy saving compared with ball mill), low noise and small footprint.

2. The pressure adjustment method of the grinding roller is compressed by the air pressure of the flexible air spring, which can shrink freely, has no difference in rebound time, the pressing force is uniform and durable, and the production capacity is obviously improved; load start.

3. It integrates the functions of crushing, grinding, drying and grading, and has a wide range of applications. A single mill can be used for grinding of various materials.

4. In order to prevent the material from being too slippery during the grinding operation, the grinding machine is equipped with a mixing and spraying device, which is convenient for the establishment of the grinding layer of the material bed and improves the output.

5. By turning the boom arm of the oil cylinder, the grinding roller assembly is turned out to the outside of the mill for easy maintenance; the grinding roller sleeve and the grinding roller assembly become a split tapered sleeve tightening structure, which greatly improves the maintenance convenience and operation economy.

6. The control system can implement local and remote automation to realize unmanned operation

Specifications And Technical Parameters Of HVM Raw Vertical Mill

【An Introduction】
HVM vertical mill can produce both coarse powder and ultra-fine powder, and can produce coarse powder from 2 to 5mm for materials with different product fineness requirements (such as grinding shale, raw material for brick making in new wall material industry, sand making in construction industry) etc.) to 15 micron ultra-fine powder with a pass rate of 97% (such as heavy calcium powder in the paper industry, activated carbon ultra-fine powder in the chemical industry), the product fineness adjustment is highly arbitrary, and the adaptability is wide.

【Solution】
For the production of coarse powder, the type selection of vertical mill needs to adopt the structure of the powder separator with low resistance and anti-wear. At the same time, due to the large number of large particles, necessary anti-wear treatment and powder separator structure design are required to achieve reasonable powder selection output and energy consumption;
For the production of ultra-fine powder, the vertical mill should focus on the design and optimization of the powder separator. Due to the large resistance of the powder selection at this time, it is necessary to strictly control the fineness, and to prevent the large particles from running thick, excessive blade wear and damage. Problems such as abnormal vibration caused by large internal resistance of the mill. Therefore, for materials with different product fineness requirements, it is necessary to calculate and analyze the smoothness of materials and gases in the vertical mill, especially the part of the powder separator, according to the characteristics of the material, so as to determine a reasonable structure of the powder separator (such as the rotor form, the number and angle of blades, the number and angle of stationary blades), and at the same time, necessary auxiliary means should be taken to control (such as using a sealed fan for gas sealing to effectively control the running of large particles).
