Santa Rosa Asphalt Co. is a modern hot asphalt plant located in
Milton, FL. They have been a Lubrication Engineers, Inc. customer since 1993.
Pictured above is the control room of Santa Rosa Asphalt where every function of
the plant is controlled from aggregate mix to drying, as well as heat, drum
speed, conveyor speed, silo temperature and load out. Santa Rosa Asphalt has
been at this location since 1966.
Even though Santa Rosa Asphalt is a modern asphalt plant, all
of their equipment must endure conditions that are typical to all asphalt plants
such as dirt, dust, high loads, rain, summertime heat and the cold of winters.
The demands on equipment and lubricants are extreme and make LE lubricants the
lubricants of choice. In fact, Mr. Pat Turner, Plant Manager will not permit the
use of any lubricant product other than Lubrication Engineers, Inc. Even though

LE's 607 ALMASOL Vari-Purpose Gear Lubricant is used in the REX and FALK
gearboxes throughout the plant. Before in-stalling LE's 607, gearbox failure and
replacement was considered normal after 2 to 3 years, and the seals required
Since using LE's 607 AL-MASOL Vari-Purpose Gear Lu-bricant there has been no
gearbox failures and no seals have been replaced. Also, gearbox amperage
reductions have ranged from 6 to 8%!
The saddle chain, which drives the rotating drum, is lubri-cated by 9000
PYROSHIELD Syn-Gear Lubricant. Normal chain life expectancy before re-placement
is about 300,000 tons. The cost to replace the saddle chain is $25,000 in parts
and labor. The saddle chain has been in service over 600,000 tons and shows no
The trunnion bearings support the tremendous weight of the drum which is
heated to 900°F. The trunnion bearings are lubricated with LE's 3752 ALMAGARD
Vari-Purpose Lubri-cant to handle the high loads and not squeeze out of the
bearings yet still form a collar around the seals to keep dirt and moisture out.
The Astec dryer removes moisture from the aggregate and heats the aggregate
so it will readily adhere to the asphalt. The conveyor bearings that feed the
dryer were previously lubricated with a specialty lubricant. The bearings failed
regularly and required replacement 3 to 4 times every year at a cost of $1,000
for each replacement. There has been no bearing failures or replacements since
using LE's 3752 ALMAGARD Vari-Purpose Lubricant. This has generated a saving in
bearings alone of $3,000 to $4,000 per year.
Because of environmental considerations, asphalt plants must contain and
collect dust. This is accomplished in a "bag house" where rapidly moving air
captures and collects dust on large Nomex bags. Subsequently, this dust is
removed from these bags by controlled pulses of air, and is collected in a
hopper which feeds the dust back into the asphalt mix. With the previous
specialty grease the exhaust fan bearings for the bag house failed and required
replacement twice each year at a cost of $600 each. Since switching to LE's 3752
ALMAGARD Vari-Purpose Lubricant, there have been no bearing failures or
replacement in this application. This saved an additional $1,200 in bearing cost
All head and toe conveyor bearings are lubricated with LE's 3752 ALMAGARD
Vari-Purpose Lubricant to insure smooth and trouble-free operation in a
Santa Rosa Asphalt also uses 2400 DCI PLUS Diesel Fuel Supplement in it's
bulk diesel fuel tank. According to Plant Manager, Pat Turner, the most
noticeable benefit from 2400 is when "our equipment will start in the winter
cold and the equipment at the cement plant across the street won't." Santa Rosa
Asphalt Co. has not replaced any injectors since adding 2400 DCI PLUS to their
diesel fuel storage tank.
