Fabrication and maintenance of dryer 6 coils
Fabrication of five coil sections in super duplex steel for dryer 6 of the Chuquicamata smelter, with their installation, repair of the dryer shell, and replacement of the piping and electrically actuated valves. Workforce of 140 on rotating shifts.
The dryer is a rotating drum with heated tube bundles inside, the coils, which remove moisture from the concentrate before smelting. LTF fabricated five new coil sections in super duplex steel, between China and its Calama shop, including the welding, bending and drilling of the matrices.
On site, the existing sections were removed and the new ones installed, the dryer shell was repaired with plates and welding, and the piping system and electrically actuated valves were replaced. 140 people took part on a rotating shift system.

- 01
Fabrication of 5 dryer coil sections in super duplex steel, between China and the Calama shop
The coils are the heated tube bundles that, inside the dryer’s rotating drum, remove moisture from the concentrate before smelting.
- 02
Super duplex welding, bending and drilling of matrices
Fabrication of each section included the super duplex welding, the bending and the drilling of the matrices.
- 03
Removal of the old sections and installation of the new ones
On site, the existing sections were removed and the new ones installed through the dryer mouth, with the sections lifted into place.
- 04
Repair of the dryer shell with plates and welding
The shell is the outer casing of the dryer’s rotating drum. It was repaired with plates and welding, including work inside it.
- 05
Replacement of the piping system and electrically actuated valves
Besides the coils, the dryer’s piping system was replaced along with its electrically actuated valves.
- 06
Workforce of 140 on a rotating shift system
140 people took part on a rotating shift system, with crews at the mouth and inside the dryer.
