Guangdong Jiangmen Lithium Automated Pneumatic Conveying Project

Project Overview

A leading lithium battery material manufacturer in Jiangmen, Guangdong, required a reliable solution for transferring sensitive powdered materials between processing stages. The existing manual handling method led to dust dispersion, material contamination, and inconsistent batch quality. Headpowder was engaged to design and deploy an automated pneumatic conveying system tailored for lithium-based powders.

Customer Challenges

The customer faced high levels of airborne dust during material transfer, which not only compromised workplace safety but also caused material loss and cross-contamination. The manual process was labor-intensive and slow, resulting in production bottlenecks and inconsistent feed rates. Additionally, the hygroscopic nature of lithium powders demanded a sealed, moisture-controlled environment that conventional conveyors could not provide.

Headpowder Solution

Headpowder implemented a closed-loop pneumatic conveying system featuring positive pressure dense-phase transport. The system uses a nitrogen-based inert gas source to prevent moisture ingress and mitigate oxidation risks. Automated valves and level sensors ensure precise batch transfer without operator intervention. A centralized PLC controller integrates with the plant's existing SCADA system, providing real-time monitoring and data logging. The solution eliminated dust emissions, reduced material waste by over 95%, and increased throughput by 40% compared to the previous method.

System Advantages

The headpowder system delivers consistent material flow with minimal degradation of particle morphology. The sealed pipeline design maintains a stable microenvironment, preserving the chemical properties of lithium compounds. Energy consumption is lower than traditional dilute-phase systems due to optimized air-to-material ratios. Maintenance is simplified through modular components and quick-release couplings, allowing filter cleaning and pipe inspection without line shutdown.
