arge girth gear drives have proven effective in plant
engineering for many decades and their reliability and
operational safety is of the utmost importance. Given
the total cost of such equipment as well as its impact on
production performance, cement manufacturers must adopt the
right maintenance strategy for each life stage of a gear. Four
maintenance strategies can be distinguished:
f
Curative: Repair after damage to return to normal operation.
f
Preventive: Perform routine maintenance for sustainable
operation.
f
Predictive: Minimise unplanned shutdown.
f
Proactive: Implement a Total Productive Management (TPM)
system for continuous improvement.
All of these strategies should be applied at the right time and
with the right resources in terms of people, the system used, and
organisational aspects, to deliver a high return on investment.
Nicolas Costa, NOVEXA,
Christoph Muschaweck, DALOG, and
Nicolas David and Dr Eva-Maria Mautner,
Klüber Lubrication, provide an innovative
approach to maximising the lifetime of
gears in the cement plant, using circular
maintenance management.
