|
| Problem: The mating area between the ball mill shell and the head would receive extreme wear from an abrasive slurry washout. The wear was so severe that the metal was worn in excess of 1/8" deep. |
|
| Solution: The complete repair area was roughened using a grinder and wire wheel attachment. Following roughening the complete area was chemically cleaned using Cleaner Blend 300. Eight holes were drill equally spaced around the diameter of the mating area. The mating area void was then sealed from the outside using PorRok. Sealing the mating area void eliminated any migration or flowing of Plastic Steel Liquid. Plastic Steel Liquid was then mixed using a drill and mixing tool. Following mixing, Plastic Steel Liquid was poured into the mating area void using a funnel. The funnel improved flow rate. Pouring started at the lowest point injection holes. A steel plate was welded over the holes when the Plastic steel would reach the hole. This process continued until the void was completely filled. Replacement of the Mill Head was estimated at $160K. Devcon cost of repair was only $10K! |
