Jiangsu Changzhou Lithium Ultrafine Dilute Phase Conveying System

This case study examines the deployment of a specialized ultrafine dilute phase conveying system at a major lithium battery material production facility located in Jiangsu, Changzhou. The project was undertaken to address critical material handling challenges associated with the transport of ultrafine lithium compounds used in cathode and anode manufacturing.

Customer Challenges

The client, a leading manufacturer of battery-grade lithium powders, faced several operational difficulties during the transfer of ultrafine (sub-micron to micron-sized) materials. Traditional mechanical conveying methods caused frequent blockages due to particle agglomeration and electrostatic buildup. High dust generation led to material loss, environmental compliance risks, and health hazards for workers. The abrasive nature of the powders also resulted in rapid wear of equipment components, increasing maintenance downtime and replacement costs. Furthermore, inconsistent feed rates affected downstream process stability, reducing overall product quality and yield.

Solution Delivered by Headpowder

Headpowder designed and installed a fully enclosed dilute phase pneumatic conveying system specifically engineered for ultrafine lithium powders. The system utilizes controlled low-velocity air streams to keep particles suspended without compaction, minimizing degradation and preventing blockages. Advanced filtration and pressure control modules ensure zero dust leakage, meeting strict environmental standards. The conveying lines are constructed with wear-resistant materials to extend service life, while a smart PLC-based control unit provides real-time adjustment of air-to-material ratio, achieving consistent and precise material flow. The solution seamlessly integrates with the client's upstream milling and downstream packaging operations.
