Advantages of vertical grinding mill in cement processing

In the process of cement production, the use of vertical mill is mainly in the processing of cement raw materials. The limestone raw material is dried and ground by a vertival mill to obtain limestone powder and a raw material with a moisture content of less than 0.5%. The raw material powder is fed into the preheater and enters the rotary klin, where it is fired a high temperature into the raw material, and the mixed with other admixures and entered into the cement production process for production.

In the process of limestone production, the vertical grinding mill has the following advantages:

1. The vertical mill integrates fine crushing, drying, grinding, powder selection and transportation. It has the advantages of small floor space and simple process flow.

2. High grinding efficiency and low operating cost. The vertical mill uses the material layer grinding principle to grind materials, with low energy consumption. The power consumption of the grinding system is reduced by 20%-30% compared with the ball mill. There is no direct contact with metal parts during the operation of the vertical grinding mill, so the wear of the grinding body is small and the metal pollution to the product is small. Moreover, the grinding roller can be used front and back, which greatly extends the service life and reduces production costs.

3. Simple operation and convenient operation and maintenance. The vertical mill is equipped with a thin oil lubrication station, an automatic control device, a limit mechanism to prevent direct contact between the roller sleeve and the grinding plate lining, and a hydraulic station system, making the vertical mill operation simpler and operation and maintenance more convenient. .

4. The quality of the products produced is more stable and the particle gradation is more uniform. The material stays in the vertical mill for only 2-3 minutes, while it takes 15-20 minutes in the ball mill. Therefore, the chemical composition and fineness of the products produced by the vertical mill can be quickly measured and calibrated, and the quality is stable.

5. The vertical grinding mill equipment is environmentally friendly, has low noise, less dust, and a clean operating environment.
