Proposal to address internal wear
caused by contamination In hydraulic
systems, lube systems and gearboxes.
Reduce environmental impact by
producing more efficient filtration
systems for hydraulic/lube systems and
gearboxes and lubricating oils for girth
gears, pinions, couplings, etc.

• Tribology – The study of rubbing
• F = μN
– F = Force required to move the component
– μ = Coefficient of friction
– N = Force proportional to vertical force F

4. Basic Theory
• Boundary lubrication: Lubrication film is insufficient to separate the
contacting surfaces.
• Mixed Lubrication: Lubrication film partly separates the contacting
surfaces.
• Hydro dynamic Lubrication: Lubrication film completely separates the
two contacting surfaces. (Jacking oil)
• (Insert Steinbeck Diagram with illustrating figures)

5. Functions of lubrication
• Clean: Remove contaminants from components to minimize
grinding paste.
• Cool moving elements: By reducing friction and transport
heat to a place where it can be dissipated from the system
• Prevent contamination: Act as a dynamic seal. Pistons,
mechanical seal, Seal ring.
• Dampen shock: Oil dampers
• Transfer Energy: Hydraulic brakes, gear tooth contact,
compensating cylinders
• Prevent corrosion: Either providing a protective layer
between steel and oxidant or chemically neutralizing the
corrosive product.

6. Different Applications on the mine
• Rolling Bearings: Include Plummer Blocks
• White metal bearings: Winders, Main Fans, Compressors,
Mills, etc.

7. Different Applications on the mine
• Diesel Engines: Diesel Loco’s
• Open gear Lubrication: Mill Girth-gear and
pinion

8. Different Applications on the mine
• Closed Gear Lubrication: Splash Lubrication
• Closed Gear Lubrication: Oil pressure
Circulation

9. Different Applications on the mine
• Transfer energy: hydraulic systems

10. Types of Lubricants
• Industrial-type lubricants:
– Petroleum based
– Above named examples
• Synthetic Oils
– Hydrocarbon derived, Esters, Chlorinated compounds and Silicones.
– Expensive
– Used in Refrigeration systems and all type of compressors.
• Greases
– Semi-fluid product resulting from dispersion of a thickening agent in
a liquid lubricant.
– Thickened with Metallic soaps (Aluminum), Modified clays
(Bentonite) and low friction powders (Silica aerogels)

11. Additives – Oil Soluble
• Detergent dispersive:
– Prevent coalescing of products of oil oxidation
– Alkaline and combat corrosion by acidic residues from Sulfur
• Anti-wear additives (EP-additives):
– Prevent destructive metal-to-metal contact
– Activated by high pressures and high temperatures at points of
contact and form compounds with metal to prevent welding (Sulfur
and phosphorous)
• Viscosity Index (VI) Improvers
– Reduces the rate of viscosity decrease with temperature increase
– This additives brought about the introduction of multi-grade oils
(15W/40)

12. Additives – Oil Soluble
• Oiliness Improvers:
– Improve the lubricity (Stickiness to steel but lower resistance to
shearing)
• Adhesion Improvers
– Latex and synthetic rubber additives tend to improve the stickiness
of the lubricant

13. Additives – Inhibitors
• Oxidation and rust inhibitors:
– When a lubricant is subjected to high temperatures oxidation occurs
which increases the viscosity, develops acidic contaminants and form
carbonaceous matter
– Additives such as Zinc-dithiofosfate reduces oxidation and provides a
protective layer against rust.
• Anti-foam Inhibitor
– Foaming or Air entrainment of oils causes problems such as
cavitation, reduced load carrying capability and increased
temperatures.
– Silicone fluids promote air release from the lubricant
• Demulsifying Inhibitors
– Promotes separation of lubricant from moisture content

14. Additives – Solids
• Molybdenum Disulfide (MOS2)
– Increases the load carrying capacity of the
lubricant and is effective at high speeds
• Graphite
– Has a low coefficient of friction and is effective at
low speeds (Often combined with MOS2)
• Zinc/Copper/Lead Aluminum Nickel powders
– Added to greases to enhance the load carrying and
anti-seize properties

15. Types and grading
Viscosity – Measure of the internal shear
friction or resistance to flow
Absolute Viscosity – Force necessary to move
a 1cm² plane at 1m/s (poise = grams/cm²)
Kinematic Viscosity – The accepted standard
viscosity measurement throughout the
world. (𝒌𝒗 =

18. Condition Monitoring
• Continuous Monitoring – Temperature; Flow; Filter delta P; Oil level
check; visual inspections.
• Open Gear – Visually inspect contact planes; Contaminants in grease;
Profile of teeth.
• Wear rate Analysis – Material loss
– Erosion (Abrasion, Cavitation, wipe)
– Corrosion (Oxidation usually in the presence of water)
– Cutting (Manufacturing faults, Thrusting)
– Pitting (fretting, Fatigue due to overloading)

22. CIRCULATING REFINER SYSTEM
For cleaning dirty
hydraulic/gearbox oil to
specifications of new oil
in hydraulic and winder
brake systems, crusher oil
tank, ball mill reservoirs
and industrial gearboxes.

23. ONBOARD REFINER SYSTEM
Maintains oil cleanliness and
integrity at all times whilst
machine( lhd, drill rigs,
excavators, frontend loaders,
etc.)operates. Eliminates the
replacement of oil and
dramatically reduces the wear
and failures in hydraulic systems.
Saves hydraulic components(
hydraulic pumps, valves, valve
bank, servos, etc.

24. BULK OIL REFINER PLANTS
For cleaning dirty/
dispensing
hydraulic/gearbox oil to
specifications of new oil.

25. GIRTH AND PINION LUBRICATION
UNIT
The requirements for a lubricant to meet the
demands for large, slow moving girth/pinion
gears:
• One hundred present synthetic oil.
• Totally waterproof.
• Impact and shear resistant.
• Ability to contract under severe pressure.
• Ability to enhance healing in scored/pitted
gears.
• Tenacious adhesion and sealing qualities.
• User friendly and easy to apply.
• Transparent (to make inspection of
pinion/girth gear easier.)

26. BREATHER
A high performance
Breather.
Transparent casing indicates
outward breathing, absorbs
and drain moisture , prevents
solid and semi-solid particles
above 5 micron to form
ingress in gearboxes and
reservoirs/tanks.

27. Conclusion
• Oil is the blood of our machines and should be cared after
• Expenses on proper maintenance is visible costs but account for
long term savings
Results of filter installation
• No oil changes After the installation
• No down-time due to blockages in the valve panel
• Hydraulic components lasts longer
• Lower impact on the environment due fewer oil changes
