Mobil Vacuoline™ 533 helps increase oil refilling interval by 60x and lower operating temperature
Equipment: Four Roller Mill (FRM)
Plant: Wolkem India Pvt Ltd.
Address: Bayyavaram, Andhra Pradesh
Wolkem has 2 FRM, each with 4 brush mounted crushing rollers, for crushing the lime stone into fine powder as part of calcium carbonate manufacturing. Each roller of FRM has 1000ml lubricating oil capacity and was being lubricated with third-party 20W40 oil. Every 8 hours, the lubricating oil was being refilled in each of the roller. This had increased the lubricant consumption and also resulted in productivity loss due to frequent machine stops.
ExxonMobil team recommended Wolkem to use Mobil Vacuoline™ 533 for the bush mounted crushing roller lubrication & also assisted during changeover process. Mobil Vacuoline™ 500 series are formulated from high quality base stocks and a proprietary additive system that gives excellent resistance to oxidation and thermal degradation, and high level of protection against wear.
