Specialized Lubrication Solutions for Cement Manufacturing
High-viscosity asphaltic-free open gear lubricants, heavy-shock roller press greases, and high-cleanliness vertical roller mill gear oils engineered to conquer extreme kiln shell radiant heat up to 300°C, abrasive cement clinker dust, and multi-thousand-ton grinding pressures.
Cement Plant Tribology & Engineering Direct Answer
Cement rotary kilns and raw/clinker grinding mills operate under extreme industrial severities: kiln tire shell temperatures exceeding 250°C to 300°C, girth gear tooth contact pressures up to 1,800 MPa with low pitch-line sliding speeds, and high-pressure grinding rolls (HPGR) subjected to massive grinding shock loads and fine abrasive clinker dust intrusion. Standard lubricants fail rapidly, leading to girth gear pitting, roller press bearing cage collapse, and kiln stoppage. FOSS Cement Plant Lubrication Solution delivers three dedicated product lines: (1) High-Viscosity Semi-Synthetic Open Girth Gear Lubricant (base oil viscosity 3,000 to 5,000 mm²/s @ 40°C, fortified with fine solid graphite and organo-metallic anti-wear chemistry, achieving FZG scuffing stage > 12 per DIN 51354 and Four-Ball weld load > 620 kgf per ASTM D2596, sprayable through automated pulsing nozzles without clogging or bitumen build-up); (2) High-Load Roller Press Bearing Grease (formulated with high-viscosity mineral-synthetic base oil 460 mm²/s @ 40°C and solid MoS2/graphite synergy, Timken OK Load > 65 lbs per ASTM D2509) protecting spherical roller bearings on KHD and Polysius roller presses; and (3) Heavy Industrial Gear Oil L-CKD 320/460 (DIN 51517-3 CLP, Flender approved) for vertical roller mill (VRM) planetary gearboxes. This solution eliminates girth gear scoring, extends open gear service life to over 15 years, and prevents roller press catastrophic bearing failures. Supplied in UN 208L steel drums and 1,000L IBC totes.

Primary Cement Plant Application Profiles
Engineered specifically for high-stress industrial machinery, minimizing friction coefficients and extending component service life.
Rotary Kiln Girth Gears & Drive Pinions
Bitumen-free spray lubricant prevents pitting and root scuffing on 10-meter diameter kiln girth gears.
High-Pressure Grinding Rolls (Roller Presses)
Solid-lubricant grease protects spherical roller bearings against crushing shock forces and clinker powder dust.
Ball Mills & Raw Material Grinding Circuits
Heavy gear oils maintain film strength on trunnion bearings and dual-drive reduction gearboxes.
Clinker Grate Coolers & Clinker Breakers
High-dropping-point greases (260°C+) resist high ambient temperatures near clinker discharge chutes.
Batch Quality Control & Standard Verification
Strict five-stage quality checkpoint from raw base oil tank unloading to finished drum sealing.
Four-Ball EP Weld Load Verification (ASTM D2596)
Every open gear batch verified to exceed 620 kgf weld load to prevent tooth scuffing.
Automatic Spray Nozzle Pumpability Audit
Ensures cold sprayability down to -5°C without nozzle tip gumming or line plugging.
Solid Particle Fineness & Dispersion Test
Moly/graphite solids milled under 5 microns to ensure zero mechanical jamming in clearances.
24-Month Sealed Retention Archive
Archived 1L production samples stored with complete 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.
