Mining equipment lubrication schedule matrix

Equipment point	Lubricant family	Main operating risk	Selection evidence
Diesel engine	Heavy duty engine oil	Soot, heat, fuel quality and long duty cycles	OEM viscosity and performance specification
Hydraulic system	Anti wear hydraulic oil	Dust entry, water, heat and pump wear	ISO viscosity grade, OEM requirement and cleanliness target
Transmission and final drive	Approved transmission or gear oil	Shock load and high contact stress	Equipment manual, friction requirement and temperature
Wheel bearings, pins and bushes	Heavy duty grease	Impact, slow speed, dust and washout	NLGI grade, base oil viscosity, load and water resistance
Open gears	Open gear lubricant	Very high load and contamination	Gear geometry, application method and OEM approval
Compressor	Compressor oil	Heat, deposits and air quality	Compressor type, discharge temperature and OEM interval

Maintenance insight: The best lubricant is the product that meets the equipment specification and survives the actual operating condition. A famous brand or thicker grease is not a substitute for viscosity, compatibility and contamination control.

Hydraulic oil for excavators, loaders and drilling equipment

Hydraulic oil transfers power, lubricates pumps and valves, removes heat and helps carry contaminants to the filter. Selection begins with the equipment manufacturer requirement. Ambient temperature, operating temperature, pump design and condition determine whether the system needs a conventional anti wear oil, a high viscosity index formulation or another approved fluid.

Cleanliness is as important as product choice. Use sealed storage, dedicated transfer equipment, clean breathers and monitored filters. A correct oil delivered through dirty containers can still shorten component life.

Grease selection for pins, bushes and bearings

Mining grease works in heavily loaded points that may move slowly, receive shock loads and face dust or water. Maintenance teams should compare NLGI consistency, thickener type, base oil viscosity, load carrying properties, water resistance, temperature range and compatibility with the grease already in service.

• Do not mix grease thickeners until compatibility is confirmed.
• Set application quantity and interval by component condition, duty and environment.
• Clean grease fittings before connecting the gun.
• Use labelled, dedicated equipment to prevent cross contamination.
• Investigate purged grease, heat, noise and repeated bearing failure.

How Nigerian mine conditions change lubricant demand

Build a mine lubrication programme

1. Create an asset register with every lubricated point.
2. Record the OEM product requirement, fill volume and service interval.
3. Standardise products only where specifications and compatibility allow it.
4. Label stores, transfer containers and application tools.
5. Use oil analysis and inspections to identify contamination and abnormal wear.
6. Track consumption, leaks, failures and overdue lubrication tasks.
7. Review products when equipment, duty or operating condition changes.

Questions to send with a mining lubricant enquiry

• Equipment make, model and component
• OEM specification and current product
• Operating hours and service interval
• Ambient and observed operating temperature
• Dust, water, shock load and slope conditions
• Storage location, pack size and delivery site
• Any current failure, contamination or consumption concern

Can one grease be used across the entire mine?

Only where every component requirement, temperature, load and compatibility condition is satisfied. Product consolidation should be evidence based.

Should a thicker oil be used when equipment runs hot?

Not automatically. Heat can indicate overload, contamination, cooling or mechanical problems. Follow the OEM viscosity range and investigate the cause.
