The challenge

The flow of rock and ore wears down chutes and high-tonnage equipment. Repairs have to be completed within the window of each plant shutdown.

How we did it

We go in during the shutdown and renew the wear liners: replacing and welding steel plates, hardened polymer plates (lighter and faster to change) and wear bars at the highest-impact points. We seal with ceramic paste and weld damaged structures. When the shutdown allows, we measure thicknesses and certify with dye penetrant testing.
