This article presents a professional case study of a closed pipe pneumatic conveying system for lithium battery filler powder, implemented in Hannover, Germany. The project, executed by Shandong Haide Powder Engineering Co., Ltd. (hereinafter referred to as Haide Powder), demonstrates the company's expertise in delivering high-efficiency, dust-free material handling solutions for the global battery materials industry. The systems described are fully enclosed, ensuring zero leakage and compliance with strict environmental standards.
In the heart of Germany's industrial region, a leading lithium battery materials manufacturer faced critical challenges in transporting fine, abrasive filler powders from storage silos to mixing and coating stations. The existing manual handling method caused significant dust emissions, product contamination, and worker safety risks. To meet the stringent German industrial hygiene regulations and improve production efficiency, the client sought a reliable, automated solution. Haide Powder was selected to design and install a complete closed pipe pneumatic conveying system tailored to the specific properties of lithium battery filler powders—materials that are highly moisture-sensitive, electrostatic-prone, and require gentle handling to avoid particle degradation.
The core of the project is a dense-phase pneumatic conveying system operating under controlled pressure. The system utilizes a closed pipe network constructed from stainless steel with smooth internal surfaces to minimize friction and prevent powder buildup. The conveying line runs from the raw material unloading area to multiple production points across the Hannover facility, covering a total distance of approximately 120 meters with several vertical lifts and horizontal bends. Each section is equipped with pressure sensors, flow meters, and automated valves to maintain stable conveying conditions. The system is designed to handle lithium battery filler powder with a bulk density of 0.6–0.8 g/cm³ and a particle size distribution of 5–50 microns, ensuring no segregation or agglomeration during transport.
This closed pipe pneumatic conveying system offers several distinct advantages for lithium battery filler powder handling. First, the fully sealed pipeline prevents any dust leakage, eliminating the risk of cross-contamination and protecting operator health. Second, the dense-phase conveying mode uses a low air-to-material ratio, which reduces energy consumption while maintaining high throughput—up to 8 tons per hour in this particular installation. Third, the system incorporates a nitrogen purge mechanism to maintain inert atmosphere inside the pipeline, preventing oxidation or moisture absorption of the hygroscopic powder. Fourth, the control system integrates with the client's existing SCADA platform, allowing real-time monitoring of material flow, pressure, and temperature. All these features make the Hannover installation a benchmark for lithium battery filler powder pneumatic conveying in Germany.
The installation at the Hannover plant was completed in 2023, following a rigorous three-month engineering phase that included on-site surveys, computational fluid dynamics (CFD) simulations, and factory acceptance tests. The system comprises a primary conveying line from the bulk bag unloading station to an intermediate buffer hopper, and two secondary lines distributing material to three separate mixing tanks. The pipeline diameter is 150 mm, with a conveying velocity of 8–12 m/s, ensuring gentle handling of the fragile lithium battery filler powder. After six months of continuous operation, the system achieved a material loss rate of less than 0.1%, compared to the previous manual method which had a loss rate of over 2%. The closed pipe design also eliminated the need for dust collectors, reducing maintenance costs by 30%.

Haide Powder is committed to providing customized, efficient, and safe material handling systems for the global battery industry.
The lithium battery filler powder used in electrode manufacturing is extremely fine and reactive. Traditional open conveying methods can cause dust explosions, material degradation, and quality inconsistencies. The closed pipe pneumatic conveying system employed in Hannover addresses these issues through several technical innovations. The system uses a special rotary valve design with wear-resistant ceramic liners to handle abrasive powders. The pipeline is equipped with multiple cleaning ports and a pigging system to allow quick product changeover without cross-contamination. The control logic includes a dynamic pressure adjustment algorithm that compensates for varying material properties, ensuring consistent flow even when the powder's moisture content fluctuates. This level of precision is critical for producing high-quality lithium battery electrodes, where any deviation in filler powder distribution can affect battery performance.
