The vertical mill is a grinding equipment that integrates fine crushing, drying, grinding, powder selection and conveying. It is widely used in the powder of various solid materials in cement, building materials, electric power, metallurgy, chemical industry, non-metallic minerals and other industries.
The advantages of vertical roller mill compared with roller mill + ball mill
1. The output is large and the work efficiency is high. All the accessories are independently produced by chaeng.
2. The grinding roller bearing adopts the thin oil circulation lubrication method, which can ensure that the bearing works at a lower temperature, and at the same time, the quality and purity of the lubricating oil are controlled, which is beneficial to prolonging the service life of the bearing;
3, equipped with a roll device, the roller can be turned out of the mill for easy maintenance;
4. Compared with some other types of roller mills, the hydraulic system of the vertical mill has low operating pressure, low oil leakage failure rate and high safety and reliability;
5. The combined separator has high efficiency in selecting powder.
