Introduction of Coal Mill Dynamic Powder Separator

The coal mill dynamic separator is mainly used as the classification equipment in the coal powder preparation (grinding) system of the cement plant.

Application of Dynamic Powder Separator:

Coal mill dynamic powder separator is adapted to coal powder classification in the process of coal powder preparation.

Working Principle of Dynamic Powder Separator:

After grinding, the coal powder enters into the selector from the bottom along with the air flow. When rising up along the shell, large amount of coarse powder has been deposited because of the slowing down of air flow speed, then discharged through the outlet. Through fixed guide blades and rotor plate with a certain angle, the air including a lot of fine powder will form eddy, then the material will be separated into coarse powder and fine powder. This unique structure makes the material being sorted time after time, and every time sorting process is completed according to balance of specific forces. Just as the balance stable level swirling flow has been formed between the rotor and shell, which makes the material stay long time in powder selecting area, to guarantee the fineness of powder, to improve powder-selecting efficiency and whole system capacity.

Advantages of Dynamic Powder Separator :

1. Compared with the static powder separator, the system output can be increased by 20-30%;

2. Eddy current dispersing device, energy saving is more than 30-40%, and equipment resistance is small;

3. Convenient fineness adjustment and simple operation;

4. The vulnerable parts are all made of anti-wear materials or treated with anti-wear technology, with little wear;

5. Stable classification performance, stable and reliable equipment operation;

6. Effective control of the fineness and particle size distribution of the finished pulverized coal can be achieved, and the adaptability to changes in coal types is strong, which is conducive to the improvement of combustion conditions;

7. The old system has strong adaptability for transformation, short transformation period, low cost, good effect and strong reliability.
