What Are The Reasons For The Abnormal Vibration Of Large Vertical Roller Mill?

I believe everyone is familiar with the large-scale vertical roller mill. It is a large-scale mine powder equipment developed and produced for large-scale and large-scale production in recent years, and its footprint is small. Stable operation, stable product quality, etc., there will be some problems in the process of equipment operation. So what are the reasons for the abnormal vibration of large vertical roller mills?

The first is to run empty. Because the vertical roller mill runs under no load, since there is no material inside the main machine, the grinding roller and the grinding ring of the vertical roller mill will be directly impacted, and then a lot of noise and vibration will be generated in the mutual collision and friction. . Therefore, our large vertical roller mill adopts the grinding roller limit device to avoid the violent vibration caused by the broken material during the working time of the mill.

Secondly, different types of vertical roller mills have different output and fineness. If the particle size of the ground material is too small and the finished product is too fine, it is easy to cause abnormal vibration of the vertical mill. The main reason is that when the material is too fine, it is difficult to form a material layer of sufficient thickness during the grinding process, making the equipment similar to the running state of an empty machine, resulting in abnormal vibration.

In addition, if the screws and bolts connected between the components become loose or even fall off when we use the vertical mill for grinding operations, it is easy to cause abnormal vibration of the vertical mill. In addition, the abnormal vibration caused by the loosening and falling off of the screws and bolts can easily cause the unstable operation of the equipment, which brings a great safety hazard to the milling production.

Therefore, when using a vertical roller mill to process and grind materials, it is necessary to analyze the causes of the vibration according to different vibration conditions, and deal with them in time to prevent larger production failures and affect the vertical roller mill. normal operation of the machine.
