  • Study on the Method for Collecting Vibration Signals from ...

     · The higher the coal load in the mill is, the more impact energy of steel balls is absorbed by coal powder, and the lower impact energy reaches the mill shell to cause relatively small vibration, and vice versa. This conclusion has a good agreement with the result of theoretical analysis. It shows that vibration strength of mill shell can reflect accurately the information of fill level.
