    Unstable Vibration Of Roller Mills Semantic Scholar

    To study the basic cause of the unstable vibration, we first investigated the dynamic characteristics of the mill vibration in its stable state and its unstable state, using a small laboratory roller mill. This showed that the unstable vibration was due to the stickslip motion of the rollers. Further, the modal analysis showed that the natural frequency of the torsional driving system of the mill corresponded with the unstable vibration frequency.
