Problem:
Augers are precise pieces of equipment that needs to be within specification in thickness and height to
transfer the materials it was intended. The company saw that “hard-facing” the augers saw only a 14
months life expectancy and thy wanted more! The flights of the auger wear over time from abrasion of
the material against the flight walls. In this application , the customer “hard-faced” welded one auger and
coated a similar auger with Devcon’s Wear Guard Fine Load 300
Both augers went into service for 13 month to determine what method worked the best! As can be seen
from the photos, the auger with Devcon shows virtually no wear! Measurements taken indicate how
well the Devcon product has performed over hard-face welding.
Solution:
Starting at the drive end the numbers below show the wear of the four flights on the auger,. All numbers
are in millimeters with nominal flight thickness being 5/8” or 16mm. These numbers show the wear
over the past thirteen months
Hard-face welded flights: 14mm 13mm 9mm 10mm
Devcon coated flights: 22mm 20mm 21mm (22mm is slightly less than 7/8”)
Devcon’s Wear Guard High Load 300 has proven itself to be superior in extending the life of the auger.
After determining the remaining wear of the flights the Devcon coated auger would still have
approximately 12 months of additional service before wearing out. Wear Guard has doubled the life of
the auger!
Besides the extended wearing qualities of Wear Guard Fine Load the cost to coat the augers were $1044
[with 45 minutes labor to coat] compared to hard-facing which was $694/each [with 5-7 hours to coat].
The total savings to coat all 12 augurs were $25,000! All new augers will be coated before allowed in
service with Devcon’s Wear Guard Fine Load 300.
