vibration analysis to avoid the resonance. The natural frequency should be less than 0.7 fn or larger than 1.4 fn, where fn is the operation frequency of the machine. For large mill, the method based on forced vibration analysis along with free vibration analysis is recommended. The vibration amplitudes should be calculated to meet the
The results discussed in Section 4 suggest that analysis of the vibration characteristics for different levels to monitor an unmeasured parameter (i.e., level of coal powder) and to diagnose the operating modes of the mill such as mill over-load, lack of coal around the end of the tub, etc, is possible.
