Rapp-it is suitable for repairs to various locations in concentrators on mine sites.
SCOPE
The customer’s concentrator throughput was approximately 25 million TPA and had 4 main outages per year at 12-week intervals. The biggest wear issues were in pipes throughout the concentrator as the slurry was very abrasive as with most mining in grinding. Although the pipes were rubber lined and, in some cases, also ceramic lined for the high wear areas, they had the occasional pipe failure, with slurry leaking from either a pipe’s bend (elbow), flange or valve body.
SOLUTION
- 500mm slurry and coarse material piping and valve body leaks were contained and sealed up using Rapp-it Pipe Repair Bandages (100mm x 9m).
- 550mm tailings pipe line leaks were successfully wrapped and sealed using Linatex rubber and wrapped with many rolls of Rapp-it Pipe Repair Bandages (100mm x 3.6m).
- Cyclone feed spool and coarse overflow spool repairs were conducted using Rapp-it Pipe Repair Bandages (50mm x 3.6m).
- Many airline pipe pin hole leaks were detected at an early stage and wrapped and sealed using the smaller Rapp-it Pipe Repair Bandage (50mm x 3.6m).
All repairs above were able to be successfully completed using Rapp-it Pipe Repair Bandages. Rapp-it set as hard as a rock and stopped the leaks. Rapp-it withstands coarse slurry and materials very well, long enough to enable planning for the right replacement.
