Why shutdown intervals matter
Scheduled shutdowns allow mining teams to replace worn liners, inspect equipment condition, and perform essential maintenance. While necessary for safe and reliable operation, shutdowns come at a cost: lost production time, maintenance labor, and logistical expenses.
Minimising downtime is therefore a critical priority for maximising mill throughput and reducing the total cost of ownership. Extending shutdown intervals without compromising equipment integrity can unlock substantial value.
Benefits of extending shutdown intervals
- Increased production time: longer operational periods mean more ore processed between shutdowns, directly boosting throughput
- Lower maintenance costs: reducing the frequency of liner replacements and maintenance activities lowers labor and materials costs
- Reduced disruption: fewer shutdowns lessen the impact on downstream processing and overall plant scheduling
- Improved asset utilization: mills are used closer to their full capacity, enhancing return on investment
How to safely extend shutdown intervals
Extending shutdown intervals requires careful planning and technological support to manage risks:
- Advanced material technologies: using wear parts with superior durability extends service intervals naturally
- Condition monitoring & predictive maintenance: sensors and analytics enable real-time wear and performance tracking, allowing maintenance to be done precisely when needed rather than on fixed schedules
- Data-driven decision making: digital twins and analytics platforms simulate wear and predict optimal replacement timing, balancing risk and uptime
- Robust maintenance planning: detailed risk assessments and contingency planning mitigate the consequences of unexpected failures
