A method of measuring the fill level based on the vibration signal of the mill shell is researched in this paper. An accelerometer that has a large measurement range is mounted directly to the mill shell, and the vibration signals are collected off the mill shell by a data acquisition system in experiment. According to the characteristic of vibration signal of mill shell, a filter processing method is applied and RMS values of vibration signals are extracted. The comparisons between the RMS value of filtered vibration signal and other traditional feature variables of fill level are discussed. The result of comparison shows that the vibrated feature variable of fill level proposed in this paper has a better superiority and stability.
