On-line Vibration Monitoring System Improves Fault Detection

Online Vibration Monitoring System Improves Fault Detection in a SAG Mill. A copper mine site already had an extensive condition monitoring program in place. We went through their oil analysis reports regularly, sitting down with them and going through the possible faults. Every mine site has several critical machines.

Grinding Mill Foundations

Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors (gearless drives).

Grinding Mills - an overview | ScienceDirect Topics

SAG mill product feeds two parallel ball mills of 6.6 m×11.1 m (internal diameter×length), each with a 9.7 MW twin pinion drive. The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed.
