The hidden lever for mining performance
Energy-efficient lubrication
As mining companies face increasing pressure to reduce operating costs and improve asset reliability, energy efficiency has become a key strategic priority. While investments often focus on process optimisation and equipment modernisation, an often-overlooked opportunity lies in lubrication.
Mining operations consume vast amounts of energy, with mills, crushers, conveyor belts and processing equipment accounting for a significant share of electricity consumption. A large portion of this energy is lost due to friction, heat generation and mechanical inefficiencies. Selecting the right lubricant can play a crucial role in reducing these losses.
Optimising gearbox efficiency
Gearboxes are among the largest energy consumers within grinding mills and other heavy-duty mining equipment. Under high loads and harsh operating conditions, conventional lubricants can contribute to increased friction, heat, vibration and wear, reducing the amount of energy transferred into productive work.
Grinding remains one of the most energy-intensive processes in mining. A typical mill operating at 5,500kW, 90% load and 6,000 operating hours per year can consume close to 30GWh of electricity annually. Even small efficiency improvements can therefore deliver significant cost savings.
Delivering measurable results
Many mining operations continue to use conventional mineral oils and low-performance synthetic oils to lubricate critical equipment. By choosing specialty lubricants from Klüber Lubrication developed specifically to meet the demands of the mining sector, operators typically achieve energy savings of 3 – 4% per gear unit.
Klüber Lubrication has delivered energy efficiency gains across a wide range of industrial applications through the use of specialty lubricants, such as the Klübersynth MEG, GEM and GH lines. In addition to reducing energy consumption, these lubricants can extend oil service life by three to five times compared to conventional products, helping to lower lubricant consumption, maintenance requirements, and waste disposal costs.
The financial and environmental impact
For a mining mill rated at 10,000kW and operating about 6,000 hours per year, a 3 – 4% reduction in energy consumption can generate annual electricity savings of approximately $180,000 – 240,000, assuming a power cost of approximately $0.10/kWh. Across larger sites operating multiple mills, annual savings can exceed $2 million.
When validated using recognised measurement standards such as IPMVP and ISO 50015, these results demonstrate that lubrication is more than a maintenance consideration. It is a strategic lever for improving operational efficiency, and equipment longevity, delivering measurable value across the life of the asset.
