What are the unexpected situations where the vertical sand mill needs to be shut down?

Such as the lubrication system, in some cases, if the power supply system fails or the vertical grinding machine itself fails, when these failures cannot be handled under operating conditions, it needs to be shut down for maintenance. Also, there are other cases that need to be closed.
1. The bearing and motor reducer heat up rapidly, and the temperature exceeds 80. ℃.
2. When the electrical appliances of the power system fail, the electrification cannot be ruled out.
3. Sparks such as motors, smoking or abnormal sound for a period of time.
4. The lubricating oil system is abnormal, such as suddenly cutting off the oil, and the end of the bearing is overheated, and the oil volume is small, so the cause cannot be detected.
In daily use, vertical sand mills need regular maintenance, regular inspections, timely reporting of problems, and timely repairs. If a fault requires replacement of accessories, it should be stopped in time.
