Phoenix produces the world's longest pipe conveyor belt
Munich, January 2007. The world's largest pipe conveyor is being built in Peru. The underground conveyor has to conform to the city's narrowly laid-out streets, so a Phoenopipe conveyor belt from Phoenix Conveyor Belt Systems was the only possibility. The company will be showcasing its products at the world's largest construction fair, the bauma, from April 23 to 29 in Munich at booth 235 in hall C2.

The world-record-breaking 16.4-kilometer-long pipe belt carries cement clinker, at a temperature of 80° Celsius, from a cement plant down to the harbor. On the return trip from the harbor back up to the cement works, the belt is to transport coal and limestone. The center distance measures 8,172 meters. For 6.5 km of the 8.2 km long stretch, the belt runs through a square cement tunnel underneath the streets of Lima's Atacongo district, skillfully dropping more than 160 meters on its way down to the harbor. "The conveyor system had to conform to layout of the streets, which can get fairly narrow at points, and a pipe conveyor was the only way to do this," explains sales manager Bernd Küsel. In addition, the conveyor's small cross-section cuts construction costs.
The belt slated for the system is a Phoenopipe ST 2500. It rolls up into a pipe belt with a diameter of 300 millimeters. Both sides of the belt are equipped with lateral Phoenotec cords, which greatly enhance the belt's restoring force.
The conveyor belt specialists at Phoenix AG, Hamburg, are carrying out the project. The conveyor belt was delivered to Peru's Cementos Lima.
"The closed Phoenopipe belt minimizes dust buildup and material spillage along the entire route. A pipe conveyor is ideal in this case because it gets by without transfer points, where the negative impact on the environment and material spillage would be particularly high," explains Küsel.
Another crucial argument in favor of an underground solution was that it does not add more truck-congested streets to what inhabitants already have to put up with. "Every hour as much as 700 tons of cement have to be hauled down to the harbor, and 500 tons of coal and limestone shipped back uphill to the cement plant," reports Küsel. Soon the Phoenopipe belt will be taking care of the whole job.
A unique feature of the Phoenopipe steel cord belt is its Phoenotec reinforcement. It greatly ups the restoring force, and thus the trackability, of the conveyor belt. "Since separate, non-interwoven cords are involved, the lateral cords can be individually spaced to optimally satisfy the specific requirements," notes Küsel.
The pipe conveyor belt's main advantage over a troughed belt is its suitability for rough terrains. A pipe belt can maneuver tight curves without danger of the belt or the goods slipping off. The material conveyed is protected from wind and rain. This means, in turn, that the environment is also protected from the material. This type of belt is thus used mainly wherever minimizing interaction between the material transported and the environment is a key issue, and in systems with tight horizontal radii and curves.
