Magnetic Filtration for Mining

In an industry where nearly every minute of operation is planned and meticulously calculated, any unforeseen equipment failure will  have a direct impact on profitability. Unscheduled downtime, and traditional 250 hour PM maintenance periods reduce operational time and overall profitability. Increase equipment reliability through OEI Magnetic Filtration to extend the operational life of  fluids, lube oil and components of rotating equipment.

OEI has Magnetic Filtration Solutions for Underground and Surface Mining rotating equipment, and mobile and plant rotating equipment.

Surface Mining

Surface Mining has developed over time into five main forms of mineral extraction: strip, mountain-top, open-pit, dredging and highwall. These methods of extraction all use similar pieces of equipment, but one sentiment remains constant- these mile high machines have to operate in the toughest environment and take a significant amount of abuse in order to extract the hardest materials on Earth. OEI provides Magnetic Filtration Solutions for gearboxes, hydraulics, pneumatics, engine lube, coolant, water, fuel and air applications on the following pieces of mining equipment:

  • Conveyors 
  • Crushers 
  • Compressors 
  • Excavators 
  • Forklifts 
  • Generators 
  • Grader 
  • Dozers 
  • Dragline 
  • Drilling Rigs
  • Haul Trucks 
  • Saws 
  • Scrapers Scraper
  • Hydraulic and Electric Shovels 
  • Loaders 

Underground Mining

Underground Mining, requires highly specialized machinery and personnel to extract some of our society’s most valuable minerals. Such strict conditions present underground leave absolutely no room for failure. Underground mining simply cannot jeopardize the lives of personnel, equipment or the end product, so everything is strictly monitored and maintained.

Install OEI Magnetic Filters on your machines to extend equipment component life, improve equipment performance, reliability, improve safety, enhance maintenance programs and consumable parts replacement. OEI has developed filtration solutions to clean lube oil, fuels, hydraulic and coolant fluids, pneumatics and air for the following machines:

  • Continuous Miner 
  • Haul Truck 
  • Scaler Scaler
  • Scooptram 
  • Scissor Lift 
  • Shotcreter Paver
  • Shuttle Car 
  • Personnel Carrier 
  • Transmixer 

Mining Plant

Once the product is harvested it is transported to plants either on or off site to be refined. To keep equipment running at peak performance, it is important to have refining rotating equipment free of contaminants. Each stage of mineral refinement contains areas where harmful contaminants can enter your systems. Crushers are especially hard on hydraulics and gearboxes because inadequate filtration of airborne contaminants. Most hydraulics are manufactured without adequate levels of filtration, (the most damaging of which are under 4 microns) which are challenged to provide adequate efficiency in full flow filtration capability. Plant equipment needs to have high efficiency filtration to keep all lube oil and fluids clean to reduce premature wear of equipment components.
