When it is found that the vibration sense of the vertical roller mill is strong, the fault cause can be analyzed from the vibration frequency. The vibration feeling is not obvious, which is mostly caused by the dislocation or damage of the indenter.
It is necessary to check the pressurizing device and replace the indenter in time to reset it; When it is found that the vibration sense of the vertical roller mill is strong, it is mostly caused by poor infrastructure, large steel blocks or large hard materials in the vertical roller mill, damage to transmission gears and bearings, etc.

After the problem is diagnosed, appropriate treatment measures can be taken. When it is found that the foundation of the vertical roller mill sinks locally, it is mainly caused by the uneven foundation construction, so it is necessary to stop the machine for treatment and add cushions to make it reach the level; When the vibration of the vertical roller mill often intensifies suddenly, the current changes little with impact sound, and the current increases.
