Headpowder Engineering Co., Ltd., headquartered in Shandong, China, is a specialized manufacturer and system integrator in the field of pneumatic conveying, with a strong focus on advanced material handling solutions for the new energy industry. The company has recently completed a landmark project in Graz, Austria, involving the inert gas nitrogen pneumatic conveying of ternary cathode materials. This project, officially titled "Austria Graz Ternary Material Air-Isolated Nitrogen Pneumatic Conveying Project," demonstrates Headpowder's technical capability in delivering high-purity, oxygen-free material transfer systems for lithium-ion battery production lines. The Graz facility is a critical node in the European battery supply chain, and Headpowder's equipment ensures that the ternary precursor materials are transported under strict nitrogen atmosphere protection, preventing oxidation and moisture contamination during the entire conveying process.
The Austria Graz ternary material nitrogen pneumatic conveying project represents a major milestone for Headpowder in the European market. Ternary materials, also known as NCM or NCA cathode active materials, are highly sensitive to oxygen and moisture. Even trace amounts of air exposure can lead to capacity degradation, structural instability, and safety risks in lithium-ion batteries. To address this challenge, Headpowder designed a completely sealed, air-isolated pneumatic conveying system that uses high-purity nitrogen as the carrier gas. The system operates under a positive pressure nitrogen atmosphere, with oxygen levels monitored to remain below 10 ppm throughout the conveyance pipeline. This ensures that the ternary powder particles maintain their chemical integrity from the raw material storage silo to the final blending or coating stage. The Graz project includes multiple transfer points, rotary valves, nitrogen purge stations, and a centralized control system that automatically adjusts gas flow rates to prevent particle segregation or agglomeration.
Headpowder's pneumatic conveying solution for the Graz project is a customized dense-phase conveying system specifically engineered for ternary cathode materials. The system utilizes a combination of pressure vessels and venturi ejectors to move the fine powder through stainless steel pipelines with minimal breakage and wear. The conveying velocity is carefully controlled to avoid particle attrition, which is critical for maintaining the spherical morphology of ternary precursor particles. The entire conveying route is equipped with nitrogen bleed valves and pressure relief mechanisms to maintain a stable inert atmosphere even during system startup or shutdown. One of the key innovations in this project is the integration of an online oxygen analyzer that provides real-time feedback to the PLC, enabling automatic nitrogen injection to compensate for any leakage. This level of automation ensures that the Graz facility can operate 24/7 with consistent product quality. Headpowder's expertise in pneumatic conveying for ternary materials has been proven across multiple projects in Asia and Europe, and the Graz installation further strengthens the company's reputation as a reliable partner for battery material manufacturers.
Nitrogen protection pneumatic conveying is the cornerstone of Headpowder's product offering for air-sensitive materials. In the Graz project, the nitrogen gas is supplied from a dedicated liquid nitrogen storage tank, vaporized, and then distributed to multiple conveying lines. The system uses a closed-loop nitrogen recirculation design to reduce gas consumption and operational costs. The nitrogen is filtered and dried to a dew point below -60°C before entering the conveying circuit, ensuring that no moisture is introduced into the material stream. The conveying lines are double-walled in critical sections, with an annular space filled with nitrogen to act as an additional barrier against air ingress. All rotating equipment, such as discharge valves and rotary feeders, are equipped with nitrogen-purged seals to prevent leakage. For the ternary material, which is both abrasive and hygroscopic, the conveying pipeline is lined with a wear-resistant ceramic coating to extend service life. The Graz facility has been operating for over 18 months without any oxygen breakthrough incidents, validating the reliability of Headpowder's nitrogen protection design. This technology is now being adopted by other battery material plants in Europe and North America seeking to meet the highest purity standards.
This Austria Graz pneumatic conveying case study highlights Headpowder's ability to integrate complex material handling systems in a brownfield industrial environment. The project scope included the design, fabrication, installation, and commissioning of a complete nitrogen pneumatic conveying line for ternary material with a throughput capacity of 5 tons per hour. The material conveyed is a nickel-rich NCM precursor with a particle size D50 of 10 microns. The conveying distance is approximately 120 meters with a vertical lift of 15 meters. To accommodate the existing plant layout, the pipeline routing included multiple bends and a 90-degree elbow, all of which were designed with a large radius to minimize material degradation. The system is controlled by a Siemens PLC with a HMI touch panel that displays real-time nitrogen flow, pressure drop, and oxygen concentration. The Graz project also included a nitrogen recovery system that captures and recycles exhaust gas, reducing the overall nitrogen consumption by 35%. This case study demonstrates that Headpowder's pneumatic conveying technology is not only effective for protecting ternary materials but also energy-efficient and cost-effective. The success of this project has led to a follow-up order for a second line at the same Graz facility, further confirming the customer's satisfaction.
