Mobil DTE 10 Excel 46 Reduces Mine's Equipment Downtime

TISCO Mining Co. Ltd.’s Jianshan iron mine introduced 35 sets of BELAZ dumpers with hydraulic sumps of about 200 liters and carrying capacities of up to 130 tons. Using a conventional hydraulic oil, the dumpers experienced high operating temperatures averaging 100°C (212°F) during the summer, which caused unscheduled downtime to occur as a result of heating. In an effort to improve equipment productivity, the mine approached ExxonMobil to identify a lubricant solution that could help reduce operating temperatures.


ExxonMobil engineers recommended TISCO Mining Co. Ltd. switch to Mobil DTE 10 Excel™ 46 hydraulic oil for the hydraulic system of the dumpers. Formulated with high viscosity index base oils and an additive system that provides excellent frictional properties, Mobil DTE 10 Excel 46 oil also provides outstanding oxidation and thermal stability in severe service hydraulic systems.


After transitioning to Mobil DTE 10 Excel 46 hydraulic oil, the company reported that operating temperatures in the dumpers were reduced to 60°C (140°F). The switch has also helped reduce unscheduled downtime and increase mine output, generating a company-estimated savings of US $823,746.
