Based in Shenzhen, Guangdong, a leading new energy enterprise recently implemented a state-of-the-art electrolyte powder conveying system designed to handle high‑purity electrolyte powders used in battery manufacturing. The project, delivered by Shandong Headpowder Engineering Co., Ltd. (branded as headpowder), focuses on a nitrogen circulation pneumatic conveying engineering solution that ensures safe, oxygen‑free transport of sensitive materials. The system integrates advanced nitrogen blanketing technology to maintain inert atmosphere throughout the conveying process, preventing moisture absorption, oxidation, and contamination — critical for preserving the electrochemical performance of electrode materials.
Electrolyte powder, a key component in lithium‑ion batteries and other new energy storage devices, demands precise handling due to its hygroscopic nature and reactivity. Traditional mechanical conveying methods often introduce air, causing degradation and quality loss. headpowder’s nitrogen circulation pneumatic conveying engineering eliminates these risks by continuously recirculating nitrogen gas in a closed loop. This approach not only protects the material but also reduces nitrogen consumption, lowering operational costs for the customer. The system is designed to handle fine, cohesive powders with minimal particle breakage, ensuring consistent particle size distribution — a vital parameter for battery slurry preparation.
The project scope included the design, fabrication, installation, and commissioning of a complete electrolyte powder conveying line with a capacity of 5 tons per hour. The system employs a dense‑phase pneumatic conveying principle under nitrogen pressure, where the powder is transported in a slug flow regime to minimize wear and energy consumption. Key components include a nitrogen booster compressor, a precision‑engineered rotary valve feeder, a gas‑solid separator (cyclone plus bag filter), and a PLC‑based control system with real‑time monitoring of pressure, flow rate, and oxygen concentration.
To meet the stringent safety requirements of the new energy materials sector, the entire conveying pipeline is constructed from 316L stainless steel with electropolished interior surfaces to prevent material adhesion and bacterial growth. All joints are welded using orbital welding technology and undergo helium leak testing to ensure zero gas leakage. The nitrogen circulation loop is equipped with an oxygen analyzer that triggers an automatic shutdown if oxygen levels exceed 1%, guaranteeing a fully inert environment. This design aligns with the highest industry standards for handling flammable and explosive powders, making it suitable for both cathode and anode electrolyte powder applications.
The system also features a dedicated nitrogen regeneration unit that recovers and purifies the exhaust gas, achieving a nitrogen utilization rate of over 95%. This significantly reduces the total cost of ownership compared to once‑through nitrogen systems. The customer reported a 30% reduction in nitrogen consumption and a 40% improvement in product consistency after switching from manual handling to headpowder’s automated solution.
headpowder’s expertise in pneumatic conveying for new energy materials is built on decades of engineering experience. The company, headquartered in Shandong, China, specializes in turnkey solutions for fine powder handling, with a particular focus on electrolyte powder conveying, battery material transfer, and chemical powder processing. The nitrogen circulation approach offers several distinct advantages over conventional methods:
For the Shenzhen enterprise, these benefits translated directly into improved product quality, reduced scrap rates, and faster production cycles. The system’s modular design also enables future expansion to accommodate increased production volumes without major civil works.
The project was executed in three phases over a period of eight months. Phase I involved site survey and process simulation, where headpowder’s engineering team analyzed the customer’s material properties (bulk density, particle size distribution, moisture content, and flowability) to optimize the conveying parameters. Phase II covered equipment fabrication and factory acceptance testing (FAT), during which the complete system was assembled and tested at headpowder’s manufacturing facility in Shandong. Phase III included on‑site installation, commissioning, and operator training, supported by a dedicated project manager from headpowder.
During commissioning, the system achieved a conveying rate of 5.2 tons per hour, exceeding the design specification by 4%. The oxygen concentration in the conveying line remained consistently below 0.5%, well within the customer’s safety threshold. The customer’s quality control team reported that the electrolyte powder exhibited zero moisture pickup and no visible agglomeration after conveying, compared to previous batches that showed up to 2% moisture increase. The nitrogen consumption averaged 15 Nm³ per ton of powder, 20% lower than the initial estimate.
The new energy enterprise’s production manager commented: “headpowder’s nitrogen circulation pneumatic conveying engineering has revolutionized our powder handling process. We no longer worry about material degradation, and the system’s reliability is outstanding. The automated data logging also helps us meet strict traceability requirements from our downstream battery manufacturers.”
