① Mechanical reason: during the initial design and installation of the vertical roller mill, due to the insufficient strength of the foundation design, there were problems in the installation and calibration, and the mill vibrated greatly. If the internal structure of the mill is inconsistent in size during the manufacturing process, the vibration of the mill will also be too large, such as the installation angle of the grinding roller is unqualified, the bottom plate of the slag discharge bin is uneven, and the height of the lining plate of the grinding disc is different.

 

② Electrical reason: during the installation of electrical equipment of the mill, if the vibration meter fails or the shielded cable is not selected correctly, it will also cause a false alarm of mill vibration and a large vibration value of the mill.

 

③ Process operation: excessive or insufficient feeding, too high or too low discharge temperature of vertical roller mill, and large or black materials entering the mill during mill operation will cause vibrations of the large mill. In short, the vibration of a vertical mill is caused by many factors. In the process of daily operation and maintenance, to accurately judge the cause of vibration, it must be comprehensively judged and analyzed in combination with the operating parameters of the mill and the operation of field equipment.
