Regarding the vibration of vertical roller mills, only by comprehensively understanding its causes can we study and solve the problem step by step.. Reason 1: The anchor bolts are loose. This phenomenon is relatively common. The reason is that when using a vertical roller mill, vibrations can cause the bolts to loosen, which exacerbates the vibration.

Rolling mill is the core equipment in modern iron and steel industry, and the reliability of its mill roll system (MRS) is the key to ensure the rolling process with high precision, high speed, continuity and stability. However, the MRS possesses some features such as high nonlinearity, time variability and strong coupling. The vertical vibration easily happens in its working process.
