Coeur Mexicana, S.A. de C.V., a Mexican mining company, operates a ball mill driven by a Falk helical gear reducer. Lubricated with a conventional mineral oil, the gearbox was operating at temperatures as high as 194°F (90°C). When the components exceed a certain high temperature threshold, the system automatically shuts down to prevent equipment breakdown, thus bringing production to a halt. In an effort to improve productivity, the company approached ExxonMobil engineers to determine an alternative lubricant solution to provide better performance under harsh operating conditions.


ExxonMobil engineers recommended transitioning to Mobil SHC™ 632 synthetic gear oil, which is designed to reduce sliding friction, resulting in increased machine efficiency and lower operating temperatures. The engineers also recommended the implementation of routine Mobil ServSM Lubricant Analysis to monitor oil and equipment condition.


Coeur Mexicana reports that Mobil SHC 632 gear oil has helped reduce operating temperatures by more than 18°F (10°C), which has helped prevent shutdowns due to high operating temperatures. The lower operating temperatures have helped prevent costly unscheduled downtime and production losses.
