In a SAG mill, most of these conditions are not valid. Speed changes, such that you may get confused by the noise coming from grinding media impacting mill shell superimposed to the standard load noise. As the global volumetric filling level is also ever changing, your only sensor may easily be fooled by the change of toe position.
