Ball Mill Shell Vibration System Analysis . Normally, there are millions of balls inside the mill. Theoretically, these balls arrange in different layers. They impact the mill shell direct or indirect with different amplitudes and periods. Thus, the mill shell vibration signal caused by these forces must be consist of sub-signals with different time

2015-1-1 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. 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).
