The vacuum degree of the oil return pipe of the ultrafine vertical mill determines the oil level in the ultrafine vertical mill cavity. The adjustment of the vacuum degree and pressure is directly related to the lubrication state of the ultrafine vertical mill bearing. If the oil level is too high or too low, it will cause oil leakage or bearing damage to the ultrafine vertical mill.
Due to the importance of the roller lubrication system to the bearing of the vertical mill, a simple method can be used to quickly diagnose whether the roller bearing is faulty in normal production:
One is to observe the oil condition in the grinding roll on site, or to determine whether the bearing of the grinding roll is damaged by detecting the content of metal particles in the oil sample. If the content of metal particles in the oil sample is high, the bearing has been seriously damaged.
