Los Pelambres - World Record

The 12.7Km project is located at Antofagasta Minerals’ Los Pelambres Mine in Chile. The system consists of three downhill belts located inside tunnels with a total drop of 1.3km. In total they can generate up to 25 MW power!

In the Los Pelambres project, CDI developed the basic mechanical design, brake system design, PLC logic, and commissioned the conveyor.

CDI has assisted with several upgrades of this conveyor since it was originally commissioned.
