  • Vibration cement ball mill

    All machines vibrate during operation. however, only a few of these vibrations cause problems to the product or the machine itself. typically, the most damaging vibrations involve a natural resonance of the machine which significantly increases the motion of critical components. rolling mill vibration is no different.

  • Ball mill troubleshooting luoyang dahua

    A third octave gauge chatter problem can produce significant gauge variation. it can vary from a few percent of nominal gauge up to higher percentages and can even cause strip breaks. this is due to excitation of one of the natural resonances of the mill stand. commonly these natural resonances have frequencies between 100 and 150hz, but sometimes as high as 300hz. these frequencies are much higher than the bandwidth of most gauge control systems. consequently, the gauge variation is an average over several vibration cycles and so is not seen by the system.

  • Vibration and temparate montoring in ball mill

    The onset of gauge chatter vibration occurs at high rolling speed. usually you can only stop it by reducing the speed of the mill. it is rarely possible to stop the vibration by increasing speed if the mill is truly unstable. typically the amplitude of vibration will rise very rapidly in less than a second. at this vibration frequency it will be audible. without vibration monitoring equipment, this audible noise is often the only indication to the mill operator that the mill is vibrating. heshe may also feel some lower frequency modes in the ground supporting the mill housing.
