A ball bearing is a circular joint that connects a rotating part to another, usually stationary, part of a machine. It allows the rotating part to provide or receive structural support while significantly reducing the amount of friction caused by the rotation. Figure 1 shows an example of a selfaligning ball bearing.

The Peak value represents the distance to the top of the waveform measured from a zero reference. For discussion purposes we'll assign a Peak value of The PeaktoPeak value is the amplitude measured from the top most part of the waveform to the bottom most part of the waveform. The Average value is the average amplitude value for the ...

groove ball bearings are the most common type of bearing, and can handle both radial and thrust loads. Due to their lowfrictional torque, they are suitable for high speeds. In a ball bearing, the load is transmitted from the outer race to the ball and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and

Gearboxes are frequently used in the mining industry, especially for power transmission between the electric drive and the ball mill; besides the extreme complexity of a ball mill gear transmission system, the fault diagnosis by vibration analysis can be easily distorted by the presence of impulsive noises due to the ball pulses on the mill shell. Although several works in the literature are ...

The mills are currently operating seven days per week, producing approximately 3,500 tpd at the Stall mill. During, plans include trucking 1,000 tpd of ore from Lalor to the Flin Flon mill until this facility shuts down at the same time as the zinc plant. The Stall mill has two circuits with design capacities of 909 tpd and 2,182 tpd.

For the industrialscale dry ball mill, the vibration signals of the front and rear shaft seat (Su et al., 2008) and the shaft seat vibration combined with the acoustic signals under grinding zone (Si et al., 2009) were used to monitor and analyze the mill load. However, the above studies failed to analyze sensitive shell vibration signals.
