Advantage
1. High grinding efficiency and low grinding energy consumption.
2. Large drying capacity.
The vertical coal mill adopts air-swept operation. By adjusting the air temperature and air volume, it can grind raw coal with a moisture content of up to 15-20%. The drying capacity of the air-swept ball mill is limited, while the use of a vertical coal mill can solve its high moisture requirement with a large air volume.
3. The grinding particle size is large.
4. The fineness of the product can be easily controlled by adjusting the rotor speed of the static and dynamic separator, and the fineness of pulverized coal can reach R0.08≤2%. And the fineness is stable and the particle size is uniform, which is conducive to the combustion of pulverized coal, and is very suitable for grinding inferior coal and anthracite.
5. The process flow is simple, the floor area is small, the building area is small, and it can be arranged in the open air. The vertical mill integrates the five processes of crushing, grinding, drying, powder selection and conveying. The process is simple and the layout is compact 50%.
6. Low noise, less dust, and clean operating environment. The system works under negative pressure, no dust is flying, and the operating environment is clean.
7. The grinding body consumes less and has a long service life. High operating rate. Because the vertical mill is equipped with a limit device, there is no direct contact between the vertical mill roller sleeve and the lining plate, the vibration amplitude of the mill is small, the life of the grinding body is long, and the running rate is high.
