Release time:
2023-04-21
Due to the high material retaining ring of the previous mill, when the mill is running, the material enters the mill and passes through the mill roller to grind the fine powder, which is taken away by the wind by the separator, and the coarse powder returns to the mill plate to continue grinding. However, there is almost no slag discharge in the mill at this time, which leads to the fact that some large pieces that are difficult to grind or grinding slag such as stones cannot be discharged can not be discharged, thus increased, thus increasing the load of the mill, making the mill, making the mill, mill vibration 1.1 mm/s and mill output is not high.
During the shutdown of the kiln for maintenance, Huang Ping arranged technicians to reduce and adjust the height of the retaining ring. When the kiln mill was started again, the current did not exceed the rated current, with an average of 44A, the mill vibration of 0.8 mm/s, the mill output could reach 40 t/h, and the slag discharge was within the normal range. The whole coal mill system was more stable, reducing the power consumption and production load of the mill, so as to ensure the stability of coal powder in kiln production. (Zhou Jinyuan)
