Ball Bearing condition monitoring vibration analysis FFT analyzer feature extraction I INTRODUCTION A ball bearing is a type of rolling element bearing that uses balls to maintain separation between moving parts of bearing The purpose of ball bearing is to reduce the friction and support loads .
Pulverizing Ball Mill Failures Likewise they work together to eliminate the root causes of failure as is the case with the ball mill pulverizers which had produced consistently high failure rates In the other 65 of the failures the gears were turned and the bearings replaced Major rebuilds cost around $20 000 to repair while.
In a ball mill steel or stone balls are mixed with the ore and during rotation of the drum the ore is ground by friction and compression into a suitable fineness for the next step in the process The main component of all mills is a rotating drum turning with a suitable speed gearbox and motor.
In case study 2 following the change of the bearings of the grinding rolls the plant team was looking for a way to reduce the risk of bearing failure During mill operation roller surfaces wear down which results in a higher dynamic load peaks which exceed the nominal torque and in general an instable mill operation and lower performance.
Therefore whether the ball mill bearing failure can be quickly found has a great influence on its production efficiency 1 The company reminds the ball mill that the failure mode of the ball mill is mainly the wear of the tumbling surface fatigue or fretting abrasion.
