properties in wet ball mill. Mill load parameters are related to different intervals of frequency spectrum. It is difficult to select the feature of vibrationacoustic frequency spectrum due to the hyper-high dimension high collinearity and redundancy in the frequency spectrum. Therefore a feature selection method of ball mill vibration
