Thus, the factor common to both of these gears is 2 (improper set). Since we have a common factor other than one between the two gears on the ball mill we can expect to see the appearance of fractional gearmesh frequency and harmonics in our vibration data. In this case since the common factor is 2, we expect to see the

When the thickness of the layer is large, the vibration of the mill will increase. When the coarse powder is not fully ground, it will enter the outer circulation under the action of centrifugal force, so that the total amount of grinding will increase, the output at the time will be reduced, and the grinding will be reduced.

1. Liners protect the outer shell of the mill from wear liners are renewable. 2. Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge.
