This article is a comprehensive engineering case study of a PVDF powder pneumatic conveying system installed at a lithium battery raw material production plant in Da Nang, Vietnam. The project was carried out by headpowder, a well-known brand owned by Shandong Headpowder Engineering Co., Ltd., based in Shandong, China. The purpose of the system is to transfer PVDF powder from bulk bag unloading to downstream mixing and dosing equipment in a fully enclosed, dust-free and safe way. Da Nang is becoming an important industrial hub in Southeast Asia, and this project demonstrates a mature solution for the rapidly growing new energy battery material industry.

PVDF, or polyvinylidene fluoride, is commonly used in lithium-ion battery production as a binder material for electrode coatings. It offers outstanding chemical resistance, high adhesion, and good thermal stability. However, PVDF powder is one of the most difficult powders to handle. It has low bulk density, fine particle size, strong cohesion, and a natural tendency to absorb moisture and agglomerate. It is also easily charged with static electricity. If it is transferred by mechanical equipment or conventional open handling methods, the powder may block hoppers, adhere to machine surfaces, and create serious dust hazards. For these reasons, the customer in Da Nang requested a safe, sealed, low-speed pneumatic conveying system. headpowder selected a dense-phase pneumatic conveying system to provide gentle handling, high product integrity, and flexible routing.

The project scope includes a bulk bag unloading station, a vacuum receiver, a rotary airlock feeder, stainless steel conveying pipes, reverse-pulse dust filters, level sensors, and a PLC-based control system. All material contact parts are made of SS304 or SS316L stainless steel with polished inner surfaces, reducing material sticking and simplifying cleaning. The pipe route is optimized with long-radius bends and minimal dead spaces to avoid blockage. The entire line is electrically grounded to dissipate static charge. Compressed air is filtered and dried to a stable dew point before use. The dense-phase conveying mode transfers the powder as moving plugs, which reduces particle breakage, segregation and heat generation. The PLC automatically controls pressure, airflow, material level and batch weight according to the production schedule.

Since commissioning, the system has shown stable performance, very low dust emission, and reduced material loss. The plant is much cleaner, and workers no longer need to manually handle heavy bags or chemical powder. This improves safety and reduces labor intensity. The system also supports accurate batch feeding, ensuring that the electrode slurry formula remains consistent. Dense-phase conveying uses lower gas velocity and higher material-to-air ratio, so PVDF particles are not easily broken down and the pipeline is protected from excessive wear. For lithium battery manufacturers, consistency and purity of raw material directly affect battery capacity, cycle life and safety.

headpowder is the project brand of Shandong Headpowder Engineering Co., Ltd. The company is located in Shandong, China, and specializes in pneumatic conveying system design, powder processing equipment, and bulk material handling solutions.
