Proactive maintenance strategy to eliminate unexpected downtime

Our online condition monitoring services for OK™ mills let you keep a constant eye on critical operating parameters and settings, ensuring optimised mill reliability and performance.
Key benefits

• Minimise unplanned stoppages • MInimise secondary damage to equipment • Increase equipment lifetime, reliability and performance • Lower OPEX and more productivity • Achieve more sustainable operations

Sustain maximum mill performance

This service helps detect early symptoms that can’t be detected by regular on-site maintenance alone. Standard sensors on the mill monitor, for example, gas flow pressure and temperature, and hydraulic grinding pressure. With continuous monitoring, you can ensure these parameters are all consistently maintained, giving you plenty of time to take planned action before problems become severe.

Optimise uptime and reduce costs

Signals from the monitors are sent to the cloud for analysis. Experts at our Global Remote Service Centre are notified of all alarms/events, enabling them to further analyse the data and generate a report detailing our recommendations for corrective actions. Your Service Account Manager will keep you informed at all times, ensuring you have plenty of time to carry out our recommendations and avoid further problems. All our service packages can be tailored to your needs.

Case

The early onset of instability in grinding pressure caused by cylinder seal leaks was detected by this service before the more severe symptoms of lost production or product quality were seen. Replacing a piston seal during a planned maintenance schedule ensured regular production was maintained.
