Grinding, pulverizing, breaking – it’s a harsh environment

Large open gears take a severe beating on a daily basis. Challenging conditions include outdoor environment, extended service operation, dust, silica, water, extreme heat and extreme pressures. Open gear lubricants must be specially formulated to keep equipment operating at maximum efficiency. Whether you operate a ball mill, rod mill or breaker mill, LE’s Pyroshield® line of heavy-duty open gear lubricants can help protect your valuable equipment and keep it running harder and lasting longer. If you are interested in making your large open gears last longer, lowering the amount of lubricant you use, and reducing overall maintenance expenditures, Pyroshield is your open gear lubricant solution. If you are using an inferior lubricant and especially if you are still using an asphaltic-based open gear lubricant, it is time to make a change to a superior product.

LE makes high-performance Pyroshield lubricants even better

After several years of proving the superiority of Pyroshield open gear lubricants, LE improved the formula, making it even better! The improved Pyroshield formula no longer contains any heavy metals or lead. LE also increased the film strength of the lubricants, making them easier to pump – particularly for automatic lubrication systems. Finally, LE raised the viscosity index, removing temperature-based fluctuations that would be seen during actual use.

Pyroshield meets or exceeds all relevant manufacturer specifications for open gear applications. It is providing reliable lubrication in coal power generation facilities, cement kilns, and metal and mineral mining operations all over the world. Pyroshield’s ability to protect open gears from extreme pressures, heavy loads and high temperatures is virtually unequaled.

Easy conversion

Pyroshield does not require the equipment to be shut down during the conversion process. Even better, LE’s certified independent consultants can be there to assist you during the conversion process. Pyroshield can be applied manually or through automatic spay systems and clings tenaciously to the gear. Pyroshield appears translucent in use, allowing for the visual inspection of the open gear. Many of our customers actually lower the amount of lubricant they consume when changing over to Pyroshield.

Lubrication systems

Pyroshield lubricants can be used in automatic lubrication systems, which apply the lubricant to the bull or ring gear teeth at set intervals in metered amounts. Pyroshield lubricants will not clog the lube system and there are no solids to block or abrade measuring valves. It also will not accumulate on nozzles, clog or otherwise interfere with the spraying process.
