Long belt conveyors represent the pinnacle of bulk material transport engineering — spanning tens of kilometers across challenging terrain to connect mines, ports, and processing facilities. As a professional bulk material handling solution provider, ZOOMRY designs complete overland conveyor systems for mining, cement, and port applications. This article explores the world's most impressive long-distance conveyor installations and the technology behind them.
World's Longest Belt Conveyor Systems
Western Sahara – 98 km Phosphate Conveyor
The Western Sahara is home to the world's longest belt conveyor system, spanning 98 km. Constructed in 1972 by Friedrich Krupp GmbH (now Thyssenkrupp), it connects the phosphate mines of Bu Craa to the coast south of El-Aaiun. This system demonstrates that belt conveyors can economically replace truck haulage even at extreme distances — delivering continuous, reliable material transport across desert terrain for over 50 years. For comparable modern systems, ZOOMRY's long-distance curved conveyors achieve single flights up to 15 km with multi-flight networks reaching 70 km.
Dubai International Airport – 63 km Baggage Handling System
The baggage handling system at Dubai International Airport is the longest conveyor system in an airport, measuring 63 km. It combines conventional belt conveyors with tray conveyors, installed by Siemens and commissioned in 2008. This installation highlights how conveyor technology scales from bulk material handling to high-speed package logistics — both relying on the same fundamental belt transport principles.
Boddington Bauxite Mine, Australia – 31 km Single-Flight Conveyor
The longest single-flight conveyor in the world is officially located at the Boddington Bauxite Mine in Western Australia. Single flight means a single continuous system for the entire length without any load transfer points. A 31 km conveyor feeds a 20 km conveyor in this cable belt system — transporting bauxite through the challenging Darling Ranges to the Worsley Alumina mill.
This system uses cable belt conveyor technology — an alternative to traditional idler belt arrangements. Cable belt conveyors are supported by two endless steel cables (steel wire rope), which are in turn supported by idler pulley wheels, rather than the belt running directly on top of idlers. This design reduces belt tension requirements and rolling resistance over extreme distances. For modern overland systems, steel cord belts with tensile strength up to 4,000 N/mm provide comparable long-distance capability with simpler idler-based support.
Key Technologies for Long Belt Conveyors
| Technology | Description | Max Distance |
|---|---|---|
| Single-Flight Conveyor | One continuous belt without load transfer points — simplest design, highest reliability over the full distance. | Up to 31 km (Boddington) |
| Multi-Flight System | Multiple conveyors connected in series with transfer points — enables longer total distances by dividing belt tension across segments. ZOOMRY systems reach 70 km total. | Up to 98 km (Western Sahara) |
| Cable Belt Conveyor | Belt supported by two steel cables running on pulley wheels — reduces belt tension and rolling resistance for extreme distances. | 31 km single-flight |
| Steel Cord Belt | Steel cables embedded in rubber — ultra-low elongation (0.1-0.25%), tensile strength up to 4,000 N/mm. Standard for modern long-distance systems. | 15+ km single-flight |
