Recently, the vibration signal of mill shells has been studied for measuring the mill load (Das, Das, Behera, Mishra, 2011). Owing to the poor conditions in power plants, it is not easy to obtain the shell vibration signals. However, mill bearing vibration signals are more easily measured, and have concordance with mill shell vibration signals.
