Many electric generating, mineral mining and manufacturing facilities, etc. require materials to be ground or pulverized prior to fueling generator sets or being used in final product processing. Much of this material is ground in Ball, Pebble, Rod, Breaker, Autogenous or Semiautogenous (SAG) Mills. Many of these mills have large, open bull or ring gear and pinion gearsets as drive mechanisms.
Lubrication of these expensive, large open gear systems presents a unique challenge due to the harsh environmental considerations, as well as heavily loaded conditions. Grinding or pulverizing mills are exposed to cement dust, mineral dust, coal dust, temperature extremes and heavy loads. These severe conditions magnify the need for superior lubricating products.
Other types of grinding/pulverizing mills are the Bowl Mill and Roller Mill, commonly used in the pulverizing of coal to fire steam boilers in electric power generating stations. The large, enclosed gearboxes, driven by electric motors and the grinding roll journals are the key lubrication points of this equipment. Heavy loads, shock loads and jars are typical of this type of pulverizing. Grit and dust are always present and if allowed to penetrate bearing and gear housings, may quickly ruin bearings and gears.
Lubrication Engineers use highly refined 100% paraffin base oils and superior quality synthetic base stocks. These oils have vastly superior lubricating characteristics, greater oxidation resistance, tougher film strength, better lubricity and greater compatibility with hoses and seals. LE lubricants contain no hazardous ingredients, offering an environmentally friendly alternative to commercial quality lubricants.
Our own additive research and manufacturing company continually develops more effective and efficient high technology additives proprietary to LE. All this technology is incorporated into Lubrication Engineers products so that they are the finest available. These additives are MONOLEC® and ALMASOL®.
Lubrication Engineeers developed the PYROSHIELD® line of lubricants with exceptional load carrying ability, outstanding adhesiveness and ease of application at various temperatures. These revolutionary lubricants were developed especially for open gears which operate in the most severe service such as pulverizing and grinding equipment.
PYROSHIELD® offers excellent non-leaded lubricity for extreme heavy-duty sliding, open gear and shock loaded applications. There are no health and safety hazards associated with PYROSHIELD®. These non-asphaltic lubricants do not cause problems with automatic lubrication systems and provide an additonal margin in case of system fault-off. PYROSHIELD® reduces lubricant consumption and reduced gear temeperatures.
