The reason for the lack of ultrafine vertical mill lubricating oil is generally because the choice of the type of ultrafine vertical mill lubricating oil is wrong. Generally speaking, the working temperature of the roller bearing is relatively high, and the temperature inside the bearing is close to 200°C.

If the type of ultrafine vertical mill lubricating oil is wrong, the oil used for lubrication will deteriorate or evaporate due to high temperature and high pressure, thus losing the function of protecting and lubricating the roller bearing, which will increase the heat generated by the friction of the roller bearing. , Resulting in an abnormal increase in bearing temperature.

In addition, if the ultrafine vertical mill lubricating oil is too little, or if it is not replaced in time, it may cause the ultrafine vertical mill lubricating oil to lose its original function, resulting in insufficient lubrication of the roller bearing, and will also increase the bearing temperature and cause premature damage to the bearing.
