The Role of Vibration Monitoring in Predictive Maintenance
2.3 Predictive Maintenance Predictive Maintenance (PdM) is the process of monitoring the condition of machinery as it operates in order to predict which parts are likely to fail and when. In this way, maintenance can be planned and there is an opportunity to change only those parts that are showing signs of deterioration or damage.

SAG Mill Grinding Circuit Design
Unlike a concentrator with multiple grinding lines, conducting SAG mill maintenance shuts down an entire concentrator, so there is a tremendous focus on minimizing required maintenance time; the reline timeline often represents the critical path of a shutdown (but typically does not dominate a shutdown in terms of total maintenance effort).
