Lubrication Engineers - Mining Lubricants

Since 1951 Lubrication Engineers (LE) has manufactured and marketed a comprehensive line of specialist, heavy-duty lubricants ideal for use in the extreme, heavily loaded applications of the mining industry. Our range of lubricants includes greases, industrial oils, gear oils, hydraulic oils, compressor oils and chain lubricants. LE International has represented the Lubrication Engineers brand worldwide for over 30 years via a network of companies.

LE's key business objective is to increase the reliability and profitability of our global mining customers by providing the most technologically advanced and specialist industrial and automotive lubricants available.

Reliable lubricants

LE lubricants consistently increase the reliability and profits of our mining customers in the following ways:

• Extending service intervals (reduced lubricant consumption)
• Increasing equipment life (reduced wear)
• Reducing energy consumption (less friction)
• Improving reliability (less expensive downtime)
• Minimizing inventory (through multi-purpose products)

Anti-friction lubricants

LE lubricants are manufactured from the best 100% select paraffinic base oils, under an ISO9001:2001 certified quality system at LE's plant in Wichita, USA. Importantly, LE lubricants also contain a range of exclusive, unique and proprietary additives that provide our lubricants with superior performance. These additives include:

• Almasol® - a unique solid film additive that greatly reduces friction, heat and wear, it is also able to withstand very high loads and temperatures up to 1,038°C
• Duolec™ - provides a ‘dual’ level of anti-wear and EP protection that forms a solid-like protective layer on metal surfaces
• Monolec® - chemical liquid additive that greatly increases oil film strength, whilst reducing friction, heat and wear
• Quinplex® - provides water and moisture resistance as well as exceptional ‘tackiness’ and mechanical stability

Particular mining applications for LE lubricants include loaders, shovels, dump trucks, drag lines, crushers and ball mills.

Open gear lubricants

We manufacture Pyroshield XH gear lubricants. This is a range of extra-high viscosity, 100% synthetic open gear lubricants for use in grinding mill applications. Its unique combination of additives allows for a large reduction in lubricant and electricity consumption as well as reducing downtime and improving reliability of very expensive mills.

Heavily loaded bearing greases

Our Almagard-based lubricants take the form of multi-functional, Extreme Pressure (EP) grease for extended service under extreme conditions. These greases can be used in all types of vehicles, on and off road as well as in many plant applications. This mining lubrication product offers great tackiness, outstanding water resistance, and is rust and corrosion inhibited.

Vari-Purpose gear lubricants

LE Duolec is a range of high-performance technology gear oils developed to surpass the challenges of today's more demanding applications in the industrial and mobile mining equipment markets. Benefits include a Timken OK load of 75lbs, FZG 14th Fail Stage Pass, greater thermal stability, improved sheer resistance and superior water separation and filtration ability. Mining applications include crushers, conveyor gear reducers and more.

Wire rope lubricants

The LE 2001 Monolec wire rope lubricant is a penetrating-type lubricant providing superior load carrying capacity and corrosion resistance. Lubrication Engineers also manufacture 2002 ALMASOL wire rope lubricant. This is a coating-type lubricant that provides a self-healing film to reduce wear and fretting corrosion during mining applications.

This product also provides excellent rust prevention for steel parts. LE also manufacture the Almasol chain and cable lubricant, this product penetrates rapidly into the chain (pin area) and will not sling off easily. Almasol lubricant also provides excellent tackiness and water resistance.

Fuel supplements

LE BTU+ Diesel Fuel Improvers increase lubricity and keep filters and injectors clean, whilst inhibiting gum and sludge formation and dispersing water from diesel fuel. This product improves combustion, helps EGR system performance, retards rust and corrosion, and protects diesel fuel in cold temperatures. Diesel fuel savings of over 5% are possible with the use of this lubricant.
