Experimental investigation of vibration signal of an ...
2008-9-1 · The experiments on an industrial tubular ball mill were performed to measure the vibration of the two shafts of the mill. The vibration signals were analyzed by applying a wavelet packet approach and the obtained characteristic parameter, i.e. the vibration energy amplitude, was correlated with the filling level of the coal powder in the mill.
