  • Mill Vibration Phenomena during Cold Rolling Innoval

    The simplest type of mill vibration is found in all mills. It is a forced vibration due to roll eccentricity and so occurs at roll rotation frequencies. These frequencies are usually lower than any of the resonant frequencies of the mill stand. Therefore, gauge variation is a result of the stiffness response of the mill and the material on the mill. In some cases, at higher speeds, it is

  • Reliability Achievement Silver Award: Improving Mill

    While most of the rolls were ground with vibration levels bel ow 0.03 mils peak-peak (p-p), some rolls exceeded 0.06 mils p-p. Rolls with high vibration levels caused excitation in the DUO Mill. A roll’s performance in the DUO Mill was found to be directly related to its grind session vibration level.

  • Prediction and analysis of cold rolling mill vibration

    01.11.2020· The mill vibration data was collected from the UCM cold rolling plant. It was believed that mill chatter during cold rolling is due to abnormal periodic oscillations of the rolls in the vertical direction,. Heidari et al. used an accelerometer located at the top of the stand to detect the vertical movement of the rolling mill.

  • Progress with Grinding Aids for Vertical Roller Mills

    As a result of the higher ΔP mill, the mill vibration increases (8-10mm/s), which results in a good opportunity to test the effect of the grinding aid. In contrast to tests with ball mills, the effect of grinding aids in a VRM is already visible and audible after 10-20min.

  • What caused the grinding mill to vibrate violently?

    The material is as fine as powder, and there is no friction between the grinding roller and the grinding ring. The vibration of the host can be controlled by adjusting the speed of the host. 3. Uneven feeding If the mill suddenly appears too much or too little feed, it will cause severe vibration of the mill. The feeding amount can be controlled by adjusting the vibrating feeder. 4. Loose

  • Unstable vibration of roller mills Semantic Scholar

    The purpose of this study is to reveal the mechanism of unstable vibration occurring in the grinding operation of roller mills and to show the design guidelines for reducing the vibration. 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.
