Mining Applications

In the Indian mining sector, lube oil filtration is critical due to the extreme threat of airborne silica (quartz) and coal dust. Silica particles are harder than bearing steel; even small amounts (20–50 ppm) can rapidly destroy high-pressure heavy machinery components.

Filtration systems should be used extensively in Indian mining setups for the following major applications:

1. Heavy Earthmoving & Off-Highway Fleet (HEMM)

Open-cast mining relies on massive mobile machinery that requires rigorous micro-filtration to combat field dust and extend expensive oil drain intervals:

• Rigid Dump Trucks (100T–240T): An oil fill on large dumper trucks can easily exceed 2,000 litres. Dedicated bypass filtration machines clean engine, transmission and differential gear oils, significantly reducing oil replacement overheads.
• Hydraulic Excavators & Shovels: Electric rope shovels and hydraulic excavators use vast amounts of hydraulic fluids (such as HLP 46/68). Handheld or truck-mounted offline purifiers filter these sumps to protect sensitive multi-stage pumps and control valves from sticking.
• Draglines & Track Drives: Large planetary gearboxes on dragline swing drives and track systems suffer intense loading. Depth filtration setups handle highly viscous gear oils (ISO VG 220/320) to extract heavy abrasive contamination.

2. Fixed Infrastructure & Mining Workshops

Stationary plant components and maintenance facilities use centralized filtration to keep machinery parts operating predictably:

• Crushers & Conveyors: Primary jaw or cone crushers generate massive dust clouds. Circulating lube systems on crusher bearings and primary conveyor drives are equipped with continuous offline filtration rigs.
• Coal Mills & Handling Plants: Equipment such as wagon tipplers, bucket elevators, and coal pulverizers utilize dedicated filtration machines to extract fine coal grit from their hydraulic power packs.
• Workshop Service Rigs: Before components are reassembled or deployed back into pits, mining workshop test rigs apply multi-stage filtration machines to flush out contaminant residues from refurbished cylinders, pumps, and hoses.
