In the rapidly evolving landscape of lithium battery manufacturing, the efficient and clean handling of raw materials is paramount. This case study focuses on a groundbreaking engineering project located in Jubail, Saudi Arabia, specifically designed for the dust-free centralized conveying of PVDF (polyvinylidene fluoride) powder used in lithium battery electrodes. The project, named "Saudi Arabia Jubail Lithium Battery PVDF Powder Dust-Free Centralized Conveying Project," represents a significant leap forward in material handling technology for the Middle Eastern battery industry. At the heart of this system is the integration of advanced pneumatic conveying technology, ensuring that the PVDF powder, a critical binder material in battery cathodes, is transported from storage to production lines without any dust leakage, contamination, or material degradation. The system is engineered to meet the highest standards of cleanliness, safety, and operational efficiency, addressing the unique challenges posed by the fine, cohesive nature of PVDF powder. By implementing a fully enclosed, automated conveying loop, the project eliminates manual handling, reduces waste, and maintains a pristine working environment, which is essential for the stringent quality requirements of lithium battery production. The entire system is designed and installed by Shandong Headpowder Engineering Co., Ltd., a leading provider of pneumatic conveying solutions based in China, with a proven track record in international projects. This Jubail facility is a prime example of how modern engineering can optimize the supply chain for battery materials, supporting the global shift toward electric vehicles and renewable energy storage.
The core technology deployed in this project is a sophisticated pneumatic conveying system tailored for PVDF powder. PVDF is a high-performance polymer with excellent chemical resistance and binding properties, but its fine particle size and tendency to agglomerate make it notoriously difficult to handle. The system in Jubail utilizes a combination of dense-phase and dilute-phase pneumatic conveying, depending on the specific transport distance and material characteristics. The dense-phase mode, operating at low velocity and high pressure, minimizes particle attrition and prevents powder degradation, while the dilute-phase mode is used for longer distances to maintain consistent flow. The entire conveying line is constructed from stainless steel with smooth internal surfaces to prevent material buildup and allow for easy cleaning. A key feature is the dust-free centralized supply mechanism: the PVDF powder is fed from a central storage silo through a network of pipes to multiple dosing stations at the battery electrode mixing lines. Each station is equipped with a specially designed discharge valve that ensures zero dust emission during material transfer. The system also includes a high-efficiency filter receiver and a reverse-pulse jet cleaning system to capture any fine particles, ensuring that the exhaust air is completely clean. The control system is fully automated, with PLC-based logic that monitors pressure, flow rate, and material level in real time, allowing for precise adjustment of conveying parameters. This technology not only improves the consistency of the material supply but also significantly reduces the risk of cross-contamination, which is critical in lithium battery production where even trace impurities can affect battery performance. The Jubail project is a testament to the capabilities of Shandong Headpowder Engineering Co., Ltd. in delivering customized solutions for the most demanding applications in the Middle East.

This specific project in Jubail, Saudi Arabia, focuses on the dust-free centralized supply of PVDF powder to multiple lithium battery electrode production lines. The system was designed to handle a throughput of several tons per hour, with the flexibility to scale up as production demands increase. The main components include a large-capacity storage silo with a fluidized bed bottom to prevent bridging, a rotary valve feeder, a Roots blower for positive pressure conveying, a series of diverter valves to route material to different destinations, and a set of receiving hoppers with integrated dust collectors. The entire system is enclosed and operates under a slight positive pressure to prevent ingress of ambient dust. The control logic includes automatic sequencing of material transfer based on the level in each receiving hopper, ensuring that production lines never run out of material. Safety features include pressure relief valves, emergency shut-off controls, and explosion-proof electrical components, as PVDF powder can form combustible dust clouds under certain conditions. The system was commissioned after rigorous testing, including air velocity measurements, material flow characterization, and dust emission monitoring, all of which confirmed that the system operates well within the required environmental and safety thresholds. The successful implementation of this project has enabled the client to achieve a significant reduction in manual labor, a 99.9% reduction in airborne dust, and a consistent improvement in product quality. This case study serves as a benchmark for future battery material handling projects in the region. For further information, please contact Zhang at WeChat: 15662777102.
The pneumatic conveying system installed in Jubail operates with a conveying air velocity of 8 to 12 meters per second for dense phase and 15 to 20 meters per second for dilute phase, depending on the specific material properties and pipeline layout. The pipeline diameter ranges from 80 mm to 150 mm, with a total conveying distance of approximately 150 meters horizontally and 20 meters vertically. The system is capable of conveying PVDF powder with a bulk density of 0.5 to 0.7 g/cm³ and a particle size distribution of 10 to 200 microns. The dust emission level is less than 1 mg/m³ at the outlet, meeting the strictest environmental regulations. The energy consumption is optimized through variable frequency drives on the blower motor, resulting in a 30% reduction in power usage compared to conventional systems. The system is designed for continuous operation 24 hours a day, 7 days a week, with a maintenance interval of over 6 months. The material handling capacity is adjustable from 500 kg/h to 3000 kg/h, providing flexibility for different production scenarios.
