This article presents a detailed pneumatic conveying case from Poznan, Poland, focusing on the transport of lithium battery ultra-fine powder. The project was executed by Shandong Headpowder Engineering Co., Ltd., a leading provider of pneumatic conveying solutions based in Shandong, China. The primary challenge was to prevent bridging and clogging during the conveying of ultra-fine, cohesive powders used in lithium battery production. By combining advanced engineering with local site conditions, the team successfully delivered a reliable and efficient system that meets the high standards of the European battery industry.
The client, a major battery material manufacturer in Poznan, required a robust pneumatic conveying system to transfer ultra-fine lithium carbonate and lithium hydroxide powders from storage silos to mixing and packaging lines. The powder characteristics – extremely fine particle size (<10 µm), high moisture sensitivity, and strong electrostatic cohesion – made conventional conveying methods prone to bridging and blockages. The client had previously experienced downtime and product quality issues due to inconsistent flow. To address this, they sought a dedicated anti-bridge pneumatic conveying solution tailored for lithium battery ultra-fine powder.
Several inherent difficulties were identified during the preliminary assessment. First, the ultra-fine powder exhibited a tendency to form stable arches in hoppers and pipelines, a phenomenon known as bridging. Second, the high specific surface area of the powder generated significant static electricity, leading to adhesion on pipe walls. Third, the system needed to operate in a clean, explosion-proof environment to comply with European safety regulations for lithium battery materials. The pneumatic conveying case in Poland demanded a design that could handle these issues while maintaining high throughput and minimal degradation.
Shandong Headpowder Engineering Co., Ltd. proposed a customized dense-phase pneumatic conveying system featuring multiple anti-bridge technologies. The system included specially designed hopper discharge cones with fluidizing pads, aeration nozzles at critical bends, and a proprietary pipeline surface treatment to reduce friction. For the Poznan site, the team integrated a Poznan pneumatic conveying layout that minimized horizontal runs and used gentle acceleration zones to prevent powder compaction. The lithium battery ultra-fine powder pneumatic conveying design also incorporated a closed-loop nitrogen purge to control moisture and electrostatic charge, ensuring consistent flow without bridging. This anti-bridge pneumatic conveying approach was validated through computational fluid dynamics (CFD) simulations and pilot tests before full-scale installation.
The installation in Poznan was completed within the scheduled timeline, with local engineers receiving training on system operation and maintenance. Since commissioning, the system has operated continuously for over 12 months without any bridging incidents. The client reported a 30% increase in throughput compared to their previous equipment, along with a significant reduction in cleaning downtime. The ultra-fine powder retained its original particle size distribution and chemical properties, meeting the stringent quality requirements for lithium battery cathodes. This success has led to additional orders for similar systems in other European facilities. The Poland pneumatic conveying expertise demonstrated by Headpowder has become a benchmark for handling challenging powders in the battery industry.
