On April 6, with the slow starting of the slab feeder for transport system of Chalco Guinea’s Boffa Bauxite Mine Project, it officially began the heavy-duty test run of the ore belted transport system which is the longest in Africa with the lowest single-ton energy consumption in the world.

Huadian Heavy Industries Co., Ltd. is responsible for undertaking the key equipment long-distance belted transport system of this project. Wuxi Boton Conveyor Solution Co., Ltd., the wholly-owned subsidiary of Wuxi Boton Technology Co., Ltd., provides R&D design, manufacturing, and technical services for all conveyor belts with a total length of 48.6km, all of which adopt the technology of ultra-low rolling resistance conveyor belt independently researched and developed by Boton Conveyor.

After three hours of operation and commissioning, the system was stable and the test run was a complete success.

Chalco Guinea’s Boffa Bauxite Mine Project is located in the northeast of Boffa City, Boffa Province, Guinea, Africa. It is an important engineering project for mutual benefit and win-win sharing between China and Guinea. The system spans mangroves, roads, water systems, ravines, open-air stone forests, and other terrains, with large ups and downs. There is both horizontal bending and vertical bending, and the natural environment is harsh. After the project is completed, it will create about 2,000 jobs locally in Guinea, effectively promoting the development of local related industries.

After many tests and verifications, the ultra-low rolling resistance formula design independently researched and developed by Boton Conveyor Solution has finally passed the test certification of American CDI to meet the energy-saving needs of the design: through the ultra-low rolling resistance formula technology, the belt strength has been reduced from ST3500/4000 to ST2000/2500, and the cost of single-line conveyor belt can be reduced by more than RMB 2 Million Yuan, which greatly reduces the purchase cost for end customers and has significant economic benefits. Through the energy-saving design of non-working surface covered rubber, energy saving and consumption reduction can reach more than 15%, which can keep the later operation and maintenance cost at a relatively lower level, and break through the bottleneck that the lack of local electric energy in Guinea affects the operation of the project.

It costs only two months to complete the production and delivery of this batch of conveyor belts, after the technical design in bidding stage, the signing of contract, the delivering of samples to US CDI for inspection, and the confirming that they fully meet the low rolling resistance requirements, effectively ensuring the installation progress of equipment on the project site.
