Mobil SHCTM 632 creates a great success story by helping an Indian cement factory quadruple stacker reclaimer gearbox oil service schedule*
Dalmia Cement operates a stacker reclaimer in its Dalmiapuram plant. Lubricated with a conventional ISO 460 VG oil, the gearboxes operated at elevated temperatures and loads, resulting in shear thinning of the gear oil and the need for change-outs every 8,000 hours. In an effort to extend oil drain intervals, Dalmia Cement approached ExxonMobil to identify a Mobil industrial lubricant solution capable of withstanding these high operating temperatures.
ExxonMobil engineers recommended the company switch to Mobil SHCTM 632 synthetic oil, an ISO 320 viscosity grade. Formulated with proprietary performance additives and synthetic base oils, Mobil SHC 632 provides a much higher viscosity index and lower traction coefficient than conventional oils. In comparison, it resists high temperature oxidation and shear thinning to provide superior synthetic oil film thickness under loads and longer oil drain intervals.
After transitioning to the Mobil industrial lubricant - Mobil SHC 632 synthetic gear oil, the company used its cement plant energy meter to measure a 5.67% increase in energy efficiency and also observed a 20°C reduction in the reclaimer gearbox operating temperature.
This is one of the many examples of how Mobil industrial lubricants with its high-performance synthetic oils make every endeavour in a cement factory a great success story.
