Due to the certain rotation speed of the vertical roller mill, the larger the particle size of the grinding material, the more obvious the centrifugal effect. At this time, the grinding efficiency will decrease, and the shape of the material surface can not be maintained, and the external circulation is increased, causing vibration.

The treatment measures are: controlling the material layer to make it slightly thicker than normal, reducing the air volume and the inlet temperature, and reducing the grinding pressure. When the grinding material is too fine, most of it has been suspended in the grinding after grinding.

The capacity of the classifier is limited, and at this time, the material on the plate is less likely to cause vibration. The treatment measures are: lowering the temperature, reducing the ventilation, reducing the speed of the classifier, and increasing the water spray. The pressure setting is unreasonable or the nitrogen pack pressure is unbalanced.
