Wear Guard™ High Load
These crusher components including lid and wear plates would receive extreme abrasive wear from processing coal. The wear was so severe that the metal was completely worn through in a number of areas. Previous method of repair was to surface weld worn areas. This repair cost was estimated to be $3K.
Complete repair areas were sandblasted to a SSPC-SP5 white metal finish. Surface area was then chemically cleaned using Cleaner Blend 300. Wear Guard High Load was applied to a thickness of 1/2" replacing worn eroded metal. Wear Guard High Load was smoothed and contoured using acetone as a thinning agent following gel point. Wear Guard High Load provided a long lasting, abrasion resistant protective surface lining. Devcon's cost was $500.
