High-reliability internal & external drive pulleys and abrasion-resistant belts engineered to maintain ±0.25% to ±0.5% gravimetric accuracy under equatorial tropical conditions.
Gabon stands as one of Central Africa's most resource-endowed and economically strategic industrial centers. Anchored by world-class manganese reserves in the Haut-Ogooué province (principally Moanda and Franceville), a rapidly diversifying wood transformation cluster at the Nkok Special Economic Zone (GSEZ), expanding mineral logistics at the Owendo Port and Port-Gentil, and rising domestic cement manufacturing, the nation has accelerated its industrial automation mandates. Within these demanding operational sectors, continuous weigh belt conveyors (continuous weight feeders) serve as the indispensable technological nexus between raw extraction, precise metallurgical blending, processing control, and international maritime bulk dispatch.
As Gabon moves systematically toward the goals established under the Plan d'Accélération de la Transformation (PAT), local processing of raw materials is taking precedence over unprocessed bulk exports. Transforming raw manganese lump into value-added silicomanganese, producing refined wood pellets and biomass from sustainable forestry byproducts, and optimizing clinker milling in Ntoum require exceptionally tight dynamic weight metering. Gravimetric continuous weigh belt conveyors ensure that variations in material moisture, particle bulk density, and surge loading are instantly reconciled with Variable Frequency Drive (VFD) speed controllers to maintain uninterrupted, setpoint-accurate mass flow.
Robust weighing frames designed to endure high bulk density (2.0–2.8 t/m³) and severe abrasive friction inherent to Moanda and Bakoumba manganese extraction sites.
High-throughput continuous belt scales and vessel load-out metering systems configured for seamless integration with the Trans-Gabon Railway (SETRAG) unloading hub.
Ultra-sensitive load cells and lightweight, low-inertia dynamic belt systems calibrated for low-density sawdust, wood shavings, and industrial timber residue proportioning.
Operating dynamic weighing conveyor machinery across Gabon requires specialized engineering capable of withstanding intense equatorial weather. With annual precipitation exceeding 2,500 mm in coastal zones such as Libreville and Port-Gentil, ambient humidity levels consistently above 85%, and high ambient temperatures, standard unsealed mechanical drives and unprotected weigh bridges suffer rapid degradation, moisture ingress in load cells, and severe belt slippage.
To overcome these environmental obstacles, our weigh belt conveyor assemblies deployed in Gabon feature hermetically sealed IP68/IP69K stainless steel load cells, completely enclosed oil-cooled motorized pulleys (such as the DY1 and TDY75 series), corrosion-resistant hot-dip galvanized or epoxy-polyurethane coated heavy-gauge structural channel frames, and anti-slip chevron or diamond-grooved rubber lagging. These engineering safeguards guarantee year-round operational stability across both the wet seasons and heavy industrial load cycles.
From remote inland mining sites to high-speed coastal transshipment terminals, our dynamic weighing and drive systems deliver mission-critical gravimetric control.
In the mining hubs of Moanda and Franceville, weigh belt conveyors are deployed directly beneath primary screening silos and wash plant surge bins. Dynamic weighing feeders accurately dose raw manganese ore into secondary cone crushers, dense media separation drums, and sintering furnaces. The integration of high-torque external motorized pulleys (YTH/YDW series) ensures instantaneous start-up under full chute load conditions without belt stalling.
At the Owendo Port bulk terminal on the Gabon Estuary, continuous weigh belt scales monitor multi-thousand ton-per-hour ship loader feed streams. These certified dynamic scales prevent vessel overloading, balance ship hold distribution, and provide legal-for-trade batch totalizing records for international customs declarations, minimizing demurrage costs and vessel turnaround times.
The Nkok Special Economic Zone processes vast quantities of Okoumé, Padouk, and exotic timber. Our lightweight gravimetric weigh belt conveyors precisely regulate the feeding of wood chips and biomass shavings into drying kilns, pellet presses, and co-generation boilers, maintaining continuous combustion stoichiometry and pellet density uniformity.
At major cement manufacturing plants near Libreville (CIMGABON / Cimaf), weigh feeders control the continuous multi-component blending of limestone, gypsum, silica sand, and pozzolana into ball mills and vertical roller mills. Precision dosing ensures structural cement compliance according to international CEM-II / CEM-I standards.
