Successfully executed Africa's first high-performance aramid conveyor belt replacement, delivering the project 22 hours ahead of schedule with flawless first-time commissioning.
Powered a massive 23-kilometer fully enclosed overland conveyor system, achieving the world’s lowest energy consumption per ton of material handled.
Reduced dust emissions and acoustic pollution by over 90%, preserving pristine local mangrove habitats while driving energy expenditures down by over 30%.
The Boffa Bauxite Project serves as a core strategic cornerstone for Chinalco's international resource security, boasting a massive annual logistics capacity of 12 million tons. Situated near the equator, the project faces relentless heat and runs through highly complex, sensitive coastal mangrove ecosystems.
To align operations with world-class green mining standards, Chinalco utilizes a 23-kilometer fully enclosed overland belt conveyor network to serve as its primary logistics artery. As a critical component of this network required a comprehensive upgrade, BOTON was trusted to implement an advanced materials and engineering overhaul to secure high-throughput, eco-friendly performance.
Extreme equatorial heat drastically accelerates rubber aging on conventional belts, resulting in rapid cover wear, tracking instabilities, and high replacement frequencies.
As the mine’s sole transshipment artery, any prolonged shutdown incurs catastrophic revenue losses, demanding absolute precision and rapid execution from the maintenance team.
The long-distance line traverses protected mangrove forests and rugged ravines, enforcing zero-tolerance mandates for industrial dust migration and acoustic disruption.
Managing tension dynamics and ensuring seamless belt splicing across an ultra-long-distance overland route like the C06 line requires elite technical expertise.
To overcome the limitations of legacy fabric belts, BOTON replaced the system with a high-tensile, lightweight aramid fiber conveyor belt(). Leveraging aramid's intrinsic high modulus, extreme wear resistance, thermal stability, and minimal elongation, the solution dramatically extends the asset's service life while reducing system mass to lower structural driving tension and operational energy draw.
BOTON deployed an elite, cross-functional project engineering matrix to navigate the geographical and climatic complexities of the Guinean site. This multi-disciplinary framework successfully synchronized heavy mechanical handling, high-precision tension control, and hot splicing under intense equatorial temperatures, bypassing critical terrain barriers without compromising installation quality.
The overland system was further optimized into an intelligent, fully enclosed corridor equipped with automated tramp iron removal, material diversion controls, and remote predictive fault diagnostics. This integration ensures continuous, real-time health monitoring and automated safety adjustments across the entire 23-kilometer transit route.
