Gabon, located on the west coast of Central Africa, is undergoing a dynamic economic transformation. Historically dependent on crude oil, the Gabonese government is actively executing the Plan d'Accélération de la Transformation (PAT). This strategic initiative prioritizes the local processing of natural resources—ranging from rich mineral reserves to agricultural produce—before export. Consequently, the demand for robust, energy-efficient, and high-precision powder grinding machinery has surged across industrial zones like Nkok Special Economic Zone (GSEZ).
As a leading global hub for industrial machinery, China has emerged as the premier partner for Gabon’s industrialization. Chinese powder grinders, renowned for their technological maturity and cost-effectiveness, are crucial in unlocking value from Gabon's massive manganese deposits in Moanda, limestone reserves in Estuaire province, and agricultural products like cocoa and coffee.
By integrating advanced classification technology and automated control systems, our powder grinders enable Gabonese enterprises to meet international quality standards. Whether it is refining manganese dioxide for battery markets or producing fine calcium carbonate for local infrastructure development, our machinery bridges the gap between raw natural wealth and high-value industrial commodities.
Gabon is the world’s second-largest producer of high-grade manganese. Ultrafine milling is vital for chemical-grade manganese used in batteries and metallurgy.
Rapid urbanization in Libreville demands local cement, mortar, and paint production, requiring consistent limestone, gypsum, and clay grinding.
Milling cocoa cake, coffee beans, and cassava root into fine powders for domestic consumption and regional export within the CEMAC zone.
The company has a registered capital of 30 million yuan, covers an area of 215,000 square meters, and has a construction area of 188,000 square meters. It is divided into three production plants: Jinghua Powder, Dalier Heavy Industry, and Jinghua Equipment. There are 378 employees in total, and scientific and technological personnel account for 39.1% of the total number of employees, including 3 people with senior technical titles and 16 people with intermediate technical titles. It consists of general management department, marketing department, foreign trade department, production department, technology department, process quality department, equipment management department, finance department, supply department, and after-sales service department, engineering technology research center.
The company is mainly engaged in powder engineering technology research and development and powder equipment manufacturing. It has strong research and development capability in the powder equipment industry. It always maintains a leading position in the country with new patented technologies and advanced proprietary technologies. It currently has 41 patented technologies (among them, there are 5 invention patents) and 3 provincial scientific research achievements.
Our powder grinding systems are custom-configured to meet the unique environmental and raw material conditions of Central Africa.
With the global shift toward electric vehicles, Gabon's manganese mining sector is moving up the value chain. Raw manganese ore must be crushed, ground, and classified into ultra-fine manganese dioxide powder (D50 < 10 microns) for battery chemical manufacturing. Our CXM Ultra-fine Grinding Mills and AF Airflow Classifiers ensure precise particle sizing without contamination, maintaining the purity levels required by international battery manufacturers.
The construction boom in Libreville and Port-Gentil relies heavily on local cement plants. Our internal classification ball mills process limestone, gypsum, and clinker into high-fineness cements. The integration of closed-circuit systems prevents over-grinding, optimizes energy efficiency, and ensures consistent quality that complies with local and international construction safety standards.
Gabon's forestry industry generates significant timber waste. Utilizing our impact mills, local wood processing facilities can convert sawdust and wood scraps into high-quality wood flour. This recycled powder is a key ingredient in Wood-Plastic Composites (WPC) and clean-burning biomass pellets, promoting circular economy practices in the GSEZ Nkok zone.
To support Gabon's agricultural self-reliance programs, our food-grade jet mills and impact grinders process dried cassava, cocoa beans, and coffee beans into ultra-fine, uniform powders. Stainless steel construction (SUS304/SUS316) ensures complete hygiene, preventing contamination and preserving the nutritional profile and flavor of local agricultural goods.
The leading products are internal classification ball mill, CXM ultra-fine grinding mill, CR series impact mill, AB series jet mill, AF series airflow classifier, single box multi-stages classifier etc. The products are widely used in non-metallic mineral materials, abrasives, refractory, dyes, coatings, chemicals, metal powders, luminescent materials, electronic materials, ceramics, pesticides, papermaking, medicine, food, health care products, etc. for material crushing and classifying.
Our products are sold to domestic provinces, municipalities and autonomous regions, and play important roles in national large enterprises, such as SINOPEC, CNPC, CETC, COFCO, SINOSTEEL, SAINT-GOBAIN, BTR, CHINALCO, The Chinese Academy of Sciences, Tsinghua University, Xinhua Pharmaceutical etc. Export volume has increased significantly in recent years, and Canada, Romania, Turkey, Russia, India, Malaysia, Thailand, Serbia, South Korea, Indonesia, Venezuela have become main sales areas.




As Gabon pushes for sustainable industrialization, several key technological shifts are shaping the mineral and powder processing landscape.
With limited technical labor in remote mining areas like Franceville, automated grinding systems equipped with PLC touchscreens and remote diagnostic capabilities are becoming standard. This allows operators to monitor feed rates, temperature, and particle size output in real-time, reducing downtime and maintenance costs.
Environmental regulations in Gabon are tightening, especially in industrial zones near urban areas. Modern operations require closed-loop powder grinding systems with integrated bag filters and negative pressure systems. This guarantees 99.9% dust collection, protecting the health of Gabonese workers and the surrounding environment.
Industrial plants in Central Africa sometimes face power fluctuations. Grinding equipment integrated with high-efficiency variable frequency drives (VFDs) can adjust to power load variations, saving up to 30% in energy compared to traditional mills while protecting electrical components from voltage drops.
The shift from exporting raw ores to processing them domestically is accelerating. High-precision classifiers allow mining concession holders to produce customized powder grades for export to Europe, Asia, and other African markets, drastically increasing profit margins per ton.
