Inner Mongolia Ordos Lithium Nitrogen Protection Conveying Case

This case study examines the successful deployment of a nitrogen-protected conveying system for lithium-based materials at a production facility in Ordos, Inner Mongolia. The project was engineered to address critical material handling challenges in a high-purity lithium processing environment.

Case Overview

A leading lithium material processor in Ordos faced recurring issues during the pneumatic transfer of sensitive lithium compounds. The existing conveying method exposed the material to ambient moisture and oxygen, leading to quality degradation and safety risks. The company needed a reliable, closed-loop conveying solution that could maintain an inert atmosphere throughout the entire transport process.

Customer Pain Points

The client experienced three main difficulties: product contamination from oxygen and humidity during conveying, frequent blockages due to material agglomeration, and inconsistent nitrogen purging that increased operational costs. Additionally, manual monitoring of gas levels required constant attention, reducing overall line efficiency.

Solutions Provided by Headpowder

Headpowder designed and installed a fully integrated nitrogen-protected conveying system tailored to the client's specific throughput and particle characteristics. Key solution elements included:

• Sealed positive-pressure conveyor lines with continuous nitrogen injection to maintain oxygen levels below 0.5%.
• Automated gas flow controllers linked to real-time oxygen sensors, ensuring consistent inert atmosphere without operator intervention.
• Specially designed rotary valves and transfer points that minimize material degradation and prevent air ingress.
• Modular piping layout allowing easy cleaning and maintenance, reducing downtime.

After installation, the system delivered stable performance with zero product contamination incidents over a six-month period. Nitrogen consumption was reduced by 22% compared to previous manual purging methods, and conveying speed increased by 15% while maintaining product integrity.
