Heavy-Duty Lubrication Solutions for Mining & Quarry Machinery
Extreme-temperature multi-grade hydraulic fluids, 5% MoS2 boundary-lubricated chassis greases, and high-load crusher gear oils engineered to conquer severe shock loads, heavy abrasive dust, and 24-hour continuous extraction cycles.
Tribological Standard Definition & Engineering Direct Answer
Mining and quarry extraction machinery operates under severe tribological conditions: continuous mechanical shock loads exceeding 1,000 MPa, heavy abrasive silica rock dust, sub-zero winters down to -35°C, and summer ambient temperatures reaching +45°C. Unscheduled downtime on primary crushers or 100-ton excavators costs thousands of dollars per hour. FOSS Mining & Quarry Heavy Equipment Lubrication Solution delivers three ruggedized industrial product lines: (1) High Viscosity Index Hydraulic Oil L-HV 46/68 (DIN 51524-3 HVLP, VI >= 150, pour point -42°C per ASTM D97) preventing pump cavitation during sub-zero startup while maintaining boundary film thickness at 95°C boom cylinder temperatures; (2) Heavy-Duty 5% Moly Mining Grease (fortified with 5% solid molybdenum disulfide MoS2 and lithium complex thickener, achieving Four-Ball weld load > 400 kgf per ASTM D2596 and Timken OK load > 60 lbs per ASTM D2509) preventing pin and bushing galling under intense digging forces; and (3) Heavy Crusher Gear Oil L-CKD 320/460 (DIN 51517-3 CLP, FZG scuffing stage > 12) for cone crusher eccentric bushings and vibratory screen exciter bearings. This integrated mining package extends component life by 40% and reduces catastrophic bearing seizures to zero. Supplied in UN 208L steel drums and 1,000L IBC totes.

Primary Mining Equipment Application Profiles
Engineered specifically for high-stress industrial machinery, minimizing friction coefficients and extending component service life.
100-Ton Hydraulic Mining Excavators
L-HV hydraulic oil and 5% MoS2 grease protect boom pins, swing bearings, and travel motors under 24/7 digging.
Gyratory, Jaw & Cone Rock Crushers
Heavy-duty gear oils absorb violent shock loads when crushing granite, iron ore, and hard abrasive basalt.
Heavy Quarry Dump Trucks & Wheel Loaders
Fleet engine oils and wheel bearing greases resist dust intrusion and extended haul cycle overheating.
Vibrating Quarry Screens & Sizers
High-dropping-point greases (260°C+) resist high G-force cage fatigue and bearing raceway spalling.
Severe Duty Quality Assurance & Laboratory Auditing
Strict five-stage quality checkpoint from raw base oil tank unloading to finished drum sealing.
Four-Ball Extreme Pressure Weld Verification
5% MoS2 mining grease tested per ASTM D2596 to guarantee weld loads exceeding 400 kgf.
Sonic Shear Stability Testing (ASTM D5621)
Viscosity loss of L-HV fluids restricted under 7% after intensive ultrasonic shearing.
Karl Fischer Moisture Content Audit
Moisture levels verified strictly under 50 ppm to prevent hydraulic component rust.
24-Month Sealed Retention Archive
Retained 1L production samples stored with full QA lot traceability.
Export Packaging, Palletization & Container Loadability
Supplied in standard UN 1A1 cold-rolled steel 208L drums (80 drums per 20GP container = 16,640 liters), 180kg open-head steel drums for greases, and 1,000L IBC totes.
