Hunan Changsha Lithium Iron Phosphate Long-Distance Conveying Case

A leading battery material manufacturer in Hunan Changsha faced critical operational challenges when attempting to transport lithium iron phosphate (LFP) powder over long distances within their production facility. The client required a reliable, efficient, and contamination-free conveying solution to support their expanding capacity.

Project Background

The LFP production line in Changsha involves multiple process stages separated by distances exceeding 200 meters. Manual handling or traditional mechanical conveyors could not meet the strict cleanliness and safety standards required for high-value battery materials.

Client Challenges

The client identified several critical pain points: frequent pipeline blockages caused by the fine, cohesive nature of LFP powder; high wear rates on equipment due to abrasive particles; static electricity buildup raising fire and explosion risks; and material degradation leading to product quality inconsistency. Additionally, the existing conveying method consumed excessive energy and required frequent maintenance shutdowns.

Our Solution

Headpowder designed and installed a customized dense-phase pneumatic conveying system specifically for LFP powder over long distances. The solution included: wear-resistant pipeline materials to extend service life, integrated static elimination devices to ensure operational safety, and precise airflow control to maintain powder integrity. The closed-loop system eliminates dust leakage and prevents contamination, while the automated control interface allows real-time monitoring of conveying parameters.

Key Outcomes

After implementation, the client achieved stable, uninterrupted conveying over 250 meters with zero blockage incidents. Energy consumption was reduced by 35% compared to the previous system, and product particle size distribution remained within specification throughout the process. Maintenance frequency dropped from weekly to quarterly, significantly lowering total cost of ownership.
