Reliable fault detection on a SAG Mill with on-line ...

This paper will show the advantage of an on-line continuous vibration monitoring compared with the regular surveys using portable equipment. It will present two case studies of detecting bearing faults in a Semi Autogenous (SAG) Mill on a mining side; one in a gearbox, the other one in the motor.

Case story: Monitoring noise to prevent mill damage

The main benefits of this type of reliable SAG mill monitoring are accurate and repeatable decibel signals at the various frequencies – information that is used to protect the mills. The next phase of the project is to provide measurements that can help customers operate a SAG or AG mill optimally.

Ball Mills and Sag Mill problem | AMP Maintenance …

21-11-2007· We have two Ball Mills and one Sag Mill. We had some visual inspection on pinion and ring gears, during these inspections we found some abnormal wear on this gears (pictures show this problem in enclosure). After that we decided to do some tests as vibration and oil analysis. Result of the vibration and oil analysis tests are as a below:

Shock pulse transducers are installed on all bearing positions. Vibration transducers are installed on the input shaft DE (V) and output shaft NDE (H/A). RPM is measured using a proximity switch facing the motor shaft. Figure 2. Location of shock pulse and vibration measurements at critical points. 4.2 Condmaster setup

What's the Difference Between SAG Mill and Ball Mill ...

Based on the high throughput and coarse grind, AG mills produce coarse grinds often classify mill discharge with screens and trommel. SAG mills grinding media includes some large and hard rocks, filled rate of 9% – 20%. SAG mill grind ores through impact, attrition, abrasion forces.
