The vibration signal analysis for lab model sag mill is same as that of ball mill, but the frequency of operation of vibration signal and impact strengths are different [8]. Sag mill will require a higher value of g and BW of the sensor due to higher stiffness compared to that of ball mill (as the length of the mills is accounted).
