THE STRONGEST CONVEYOR BELT

The conveyor belts with the highest specific breaking strength are the
St 7800 steel cord conveyor belts, operating on two long distance downhill conveyors at the Los Pelambres copper mine in Chile.
The belts run at 6 m/s.
The actual breaking strength of these super belts is more than
15.000 kN.

Note: Look here for the highest total belt strength

Since it is downhill conveying, the motors generate 25 MW of power at full load of 8700 t/h.
The disk breaks have a diameter of 2,5 m. The length of the 3-part system is 12.700 m.
Almost the complete belt is operating in tunnels to protect it from the danger of avalanches in the Andes.
