Hebei Langfang Lithium Battery Powder Dust-Free Sealed Pipeline Transportation Complete Project

In the field of lithium battery powder processing and transportation, a certain company has long been troubled by issues such as dust escape, material loss, and environmental pollution caused by traditional open conveying methods. To meet increasingly stringent environmental requirements and improve production efficiency, the company introduced a dust-free, sealed pipeline pneumatic conveying system provided by Head Powder, successfully achieving fully sealed and automated operation from raw material storage to process feeding, significantly improving the working environment and material management quality.

Customer pain points

During the production of lithium battery cathode materials, the customer's powder raw materials are mostly micron-level ultrafine powders with small particle sizes and light weight, which easily generate large amounts of dust during transfer and feeding. Traditional mechanical conveying equipment (such as screw conveying and belt conveying) suffers from insufficient sealing, rapid equipment wear, and residual material cross-contamination. At the same time, with many manual operation steps, dust not only threatens operator health but also easily causes powder moisture accumulation and clumping, affecting battery performance consistency. In addition, environmental authorities continue to tighten supervision of fugitive emissions, and companies urgently need a sealed conveying solution that can achieve dust-free, low-loss, and reliable performance.

Solutions and product advantages

To address these pain points, Head Powder has customized a negative pressure dilute-phase pneumatic conveying system for them. The system adopts a fully enclosed pipeline design, ensuring zero leakage from the raw material silo to various powder points, with dust emissions approaching zero. Key components include:

• Sealed feeding device: uses a rotary feeding valve combined with a pneumatic gate valve to achieve relatively accurate and quantitative feeding, preventing external moisture and impurities from entering;
• High-efficiency air source and filtration unit: equipped with low-energy Roots fans and pulse back-blowing self-cleaning filters, ensuring clean air sources and exhaust emissions meeting environmental standards;
• Intelligent control system: Based on PLC and touch screen, it can monitor pipeline pressure, flow, material level, and other parameters in real time, enabling automatic speed regulation, fault alarms, and remote operation and maintenance;
• Wear-resistant bent pipes and inner wall treatment: To address the high hardness and strong static electricity characteristics of lithium battery powder, the pipes use wear-resistant ceramic linings or special coatings to reduce wear and material attachment.

After the system was put into operation, dust concentration in the customer's workshop dropped by over 90%, material loss rate dropped from the original 3% to below 0.5%, equipment maintenance intervals were extended threefold, and production continuity improved. The entire conveyor line, combined with a sealed ton bag unpacking station and an automatic metering system, achieves a full-process dust-free operation from unpacking, conveying, weighing to batching.

Application Effectiveness and Value

Head Powder provided this customer with a dust-free, sealed pipeline pneumatic conveying solution, which not only solves environmental and health challenges during lithium battery powder transportation but also reduces manual intervention through automation upgrades, enhancing production stability and product consistency. This system has been successfully replicated at multiple lithium battery material production bases in Hebei, Langfang, and other locations, becoming an important technical support for industry customers in achieving clean production and lean manufacturing.
