Have a ‘quarry’ about oil drain intervals? – An example from the Russian mining industry

Find out how switching to high performance oils and greases can help mine operators gain a competitive advantage. A Russian limestone quarry cut its annual lubricant-related expenditure by €7,900 by switching to a high performance oil.

Mine owners need to ensure the reliable performance of all their equipment, because any unscheduled downtime can damage bottom line performance.

In this week’s tip, we look at how operators can use high performance oils and greases, in tandem with a next generation used oil analysis service, to guarantee uptime, cut costs, and improve equipment performance – thereby gaining them a competitive advantage in an increasingly competitive industry.

A leading Russian limestone quarry faced a quandary – it had to drain its existing hydraulic oil every 4,000 hours, but was aware that its excavators, which weighed between 80 and 115 tonnes, could perform better. It approached ExxonMobil in the hope of extending oil life while maintaining hydraulic pump efficiency.

Working with ExxonMobil’s field engineering team to identify the most suitable lubricant, the mining company decided to switch to Mobil DTE 10 Excel 46 hydraulic oil, which was developed to provide a long oil life and minimise deposit formation, even in hydraulic systems operating in severe conditions. Another recommendation was to implement Mobil Serv Lubricant Analysis to monitor the in-service performance of the oil.

With this switch, the Russian business was able to:

  • Extend the optimal drain interval to 5,000 hours – an improvement of 25% on the previous grade
  • Enhance hydraulic pump efficiency
  • Reduce deposit formation and filter clogging
  • Record zero unscheduled downtime during the test period, thereby boosting productivity and reducing maintenance costs
  • All in all, achieve an annual saving of €7,900 (US$9,000)!
