The grinding roller is a component used for grinding materials in the vertical roller mill. Although it is a seemingly small component, it bears this huge pressure and vibration during operation, and the operating environment is a high temperature environment of about 200℃, so the wear is more serious. In addition, there are some other reasons, will aggravate the wear of the roller, today to explain in detail to you!

Bearing poor quality

After grinding, the bearing with poor quality, the vibration is obviously larger, and the feeding amount is low, which is easy to lead to bearing damage. In order to reduce the interruption of the entire vertical roller mill system after bearing damage, it is necessary to use good quality bearings to reduce the complexity of the process and affect the process of work.

The lubricating oil of the grinding roller is insufficient

The insufficient amount of lubricating oil on the grinding roller will make the friction between the roller and the bearing serious, produce a lot of heat, can not be distributed in time, poor lubrication effect and then affect the operation of the machine, reduce its service life.

The type of lubricating oil is poor

Lubricating oil must be selected with excellent categories and high cost performance in order to achieve certain benefits. The category of lubricating oil is poor, the lubrication effect is not good, so that a good oil film can not be formed between the bearing and the slide, the quality of the oil is poor, when the temperature rises, the color will be black, the viscosity will decline, the lubrication effect is worse, but also cause the bearing temperature is high, seriously shorten the service life of the bearing, lead to the waste of materials, seriously affect the entire project, reduce the enterprise to obtain profits.

Uneven distribution of grinding materials

Daily observation and record the situation of the grinding material, it can be found that when the material layer is too much, the work of the grinding roller will increase, the corresponding wear is more serious, and it will cause the accumulation of materials; After grinding, the material is also easy to deviate from the center of the grinding table, resulting in long-term high-load operation of the grinding roller bearing and damage to the bearing.
