Mill health inspections
Mill components need to be monitored and inspected to operate within OEM design specifications in order to achieve maximum life of the mill components. Periodic inspection is a pre-requisite for an efficient maintenance program. By monitoring and inspecting the mill and associated equipment you will obtain sufficient information to schedule maintenance on components at pre-determined maintenance shut downs, as opposed to experiencing break downs and having to undertake unplanned maintenance, directly impacting production.
- In situ inspection.
- Condition monitoring services (temperature and vibration).
- Gear radial and axial run out inspections.
- Gear root clearance.
- Gear tooth profile measurements.
- Gears and drive train alignment.
- Bearing visual and clearance measurements.
- On-site NDT inspections.
- Shell and head thickness investigations & technical assessments.
- Foundation inspections.
- Detailed reporting and record keeping.
- PLC review: instrumentation checks and ensuring control philosophy is adequate to prevent the mill against damage.
To derive the maximum benefit from both planned and unplanned maintenance, it is essential to keep an accurate history of inspection records, repairs and alterations to the original installation. NCPI will generate a report with every inspection and ensure proper record keeping, as well as assist to track condition of components.
