Dust-Free Vacuum Pneumatic Conveying System Solution for Lithium Battery Cathode Materials

In the manufacturing of power batteries, the refined, dust-free, and efficient transfer of lithium battery cathode materials (such as lithium iron phosphate LFP, ternary precursors, etc.) is critical for energy density, environmental safety, and production yields. This article details a custom dust-free vacuum pneumatic conveying system implementation engineered by BIOP for lithium powder handling.

1. Customer Pain Points & Industry Challenges

Lithium powder feeding and transfer operations typically face severe technical hurdles:

• Dust Pollution & Health Hazards: Open material handling generates fine airborne dust, degrading workshop cleanliness and threatening worker health.

• Static Adsorption & Material Losses: Fine powders prone to static buildup and mechanical collision suffer from degradation and residue, lowering overall yields.

• Inconsistent Production Rhythms: Traditional manual operations are slow and fail to integrate smoothly with upstream drying/mixing and downstream packaging systems, capping plant capacity.

2. BIOP Tailored Solution & Core Advantages

Addressing these challenges, BIOP deployed a dust-free vacuum pneumatic conveying system featuring:

1. Enclosed Vacuum Suction, Zero Dust: Negative pressure airflow draws powders securely through fully sealed pipelines, completely eliminating fugitive dust emissions at the source.

2. Low-Loss Design & Special Inner Wall Treatment: Optimized bend radiuses and anti-static/wear-resistant inner wall treatments minimize particle attrition and residue, keeping conveying losses below 0.1%.

3. Smart Integration & 30% Efficiency Boost: Integrated PLC automation modules precisely regulate conveying speeds and flow rates, seamlessly connecting with drying, mixing, and packaging lines to boost overall efficiency by approximately 30%.

4. Remote Monitoring & Fault Early Warning: Equipped with IoT intelligent control terminals to support real-time remote monitoring and automated alerts for reliable continuous production.
