Head Powder successfully delivered the complete set of positive pressure plug flow pneumatic conveying equipment project for lithium iron phosphate in Quzhou, Zhejiang, providing reliable technical support for powder conveying in the new energy materials sector. This project designed a customized positive pressure bolt flow pneumatic conveying system for lithium iron phosphate materials, addressing their tendency to absorb moisture, break easily, and agglomerate, achieving efficient, low-loss, and dust-free material flow.

Case Summary

A new energy materials company is located in Quzhou, Zhejiang, mainly engaged in the production of lithium iron phosphate cathode materials. As production capacity increases, the original conveying methods can no longer meet material quality and environmental protection requirements. Head Powder has planned and implemented a complete set of positive pressure plug flow pneumatic conveying equipment for them, covering the entire process of sealed conveying from raw material silos to batching systems.

Customer pain points

Customers face three core issues during production:

• High material damage rate: Traditional mechanical or dilute-phase pneumatic conveying causes lithium iron phosphate particles to break easily, affecting battery performance consistency.
• Moisture absorption and caking: Lithium iron phosphate is sensitive to moisture, and open or semi-open transport environments can easily cause moisture absorption, leading to agglomeration and pipeline blockages.
• Dust pollution and loss: Conventional conveying methods make it difficult to achieve adequate sealing, and dust leakage not only pollutes the workshop environment but also causes material loss and safety risks.

Product advantages

To address these pain points, Head Powder offers a positive pressure thrombo-flow pneumatic conveying system with multiple design optimizations:

• Low crushing and conveying: By accurately controlling airflow velocity and the density of the material plug formation, materials move at low speed in a 'plug flow' pattern, which reduces the probability of particle collision and breakage.
• Fully sealed and moisture-proof: The system uses airtight pipelines and high-efficiency dehumidification air sources, isolating external moisture from the source to the end of the transport, effectively preventing moisture absorption and caking.
• Intelligent dust control and collection: Equipped with multi-stage pulse dust removal and pressure monitoring devices to achieve low-emission operations, while providing real-time feedback on conveying status to reduce manual intervention.
• Customized adaptation: Based on the Quzhou project's site layout and material characteristics, optimize elbow angles, pipe diameters, and air source pressure, helping to ensure conveying stability and energy efficiency.
