The official project title is "Vacuum Conveying of Lithium Salt Powder in Lahti, Finland." The sub-headline for this European reference case is "A European Pneumatic Conveying Case Study." The key searchable keywords are: pneumatic conveying case, European pneumatic conveying, and negative pressure pneumatic conveying. This project serves as an important example of advanced powder handling technology for European customers. The system was successfully installed and commissioned at a lithium salt processing plant located in Lahti, Finland, a city known for its strict environmental regulations and modern industrial infrastructure.

Lithium salt powders present many handling challenges. They are fine, often hygroscopic, and can form explosive dust clouds. Traditional mechanical conveyors may cause powder leakage, contamination, or particle degradation. Lithium salts are essential in batteries and energy storage, so preserving product integrity is crucial. Therefore, the customer chose a negative pressure pneumatic conveying system. A vacuum pump creates a low-pressure environment in the pipeline, allowing atmospheric pressure to push the powder into the air stream. The material then flows through a closed pipe to receiving vessels with minimal product loss.

The complete engineering and equipment supply were handled by Shandong Headpowder Engineering Co., Ltd., commonly known as Headpowder. This professional engineering company is located in Shandong, China. The project manager responsible for this European project was Manager Zhang. His WeChat contact number is 15662777102. Headpowder has extensive experience in pneumatic conveying systems for lithium battery materials, fine chemicals, and other bulk solids. Their installations span many countries across Europe and Asia, demonstrating a strong track record in international projects.

For the Lahti installation, the vacuum conveying system comprised a feed hopper, rotary airlock, conveying pipeline, filter receiver, vacuum pump, and a programmable logic controller. The lithium salt powder was drawn from storage silos and gently transferred to multiple weighing hoppers. A high-efficiency dedusting filter inside the receiver prevented any powder from escaping into the atmosphere. Smooth bends and carefully selected pipe diameters reduced abrasion and particle breakage. The conveying air was dried and filtered, protecting the material from moisture and oil contamination throughout the entire process.

Negative pressure conveying provides several distinct advantages. First, the material remains fully enclosed, preventing dust emissions and enhancing workplace safety. Second, the system can easily collect material from multiple feed points and deliver it to one or more destinations. Third, because the internal pressure is lower than ambient, any small leak in the pipeline causes air to enter rather than powder to escape. Fourth, the system is compact and flexible, requiring minimal structural changes when installed in an existing plant. It also simplifies product changeovers, as the pipeline can be readily opened for cleaning and maintenance.

Since lithium salt dust is flammable, the system design complied with the European ATEX directive and CE marking requirements. All electrical components were explosion-proof, and the entire pipeline was properly grounded to prevent static electricity. The vacuum pump was located outside the process area to reduce noise and heat. Components in contact with the material were made of polished stainless steel, meeting high hygiene standards. Pressure sensors, alarm systems, emergency stop buttons, and pressure relief valves were installed to provide complete protection for operators and equipment.

During the engineering phase, Headpowder utilized computational fluid dynamics (CFD) simulations and 3D scanning to optimize the conveying line layout. The team analyzed the lithium powder's particle size, bulk density, moisture content, and angle of repose. Based on that analysis, they determined the optimal conveying velocity and pipe arrangement. This careful design minimized erosive wear and energy consumption while maintaining reliable operation. A remote monitoring platform was also provided, enabling the client to track system performance in real time. After commissioning, the plant achieved low-maintenance operation with no product quality changes.

In summary, the successful completion of the Lahti project demonstrates Headpowder's strong capability in European pneumatic conveying. It highlights the practical benefits of negative pressure conveying for lithium salt powders. For more information or potential collaboration, please contact Manager Zhang at WeChat: 15662777102.
