Head Powder's sealed, leak-free lithium battery packing powder project in Yangjiang, Guangdong, provides a safe and environmentally friendly powder treatment solution for lithium battery cathode material production. This case focuses on the conveying and feeding of high-value, dust-prone lithium battery fillers (such as lithium iron phosphate, ternary materials, etc.), achieving a fully enclosed operation process to effectively prevent material leakage and environmental pollution.

Project Background

A lithium battery materials manufacturer expanded its production line at its Yangjiang base. The original powder conveying system suffered from insufficient sealing, resulting in dust in the workshop, a high rate of material loss, and frequent shutdowns for cleaning. Head Powder was invited to provide technical evaluation and complete equipment renovation services.

Customer pain points

The main issues faced by customers include: 1) The packing powder has small particle size and poor flowability, and traditional screw or pneumatic conveying tends to cause static accumulation and pipeline blockages; 2) Failure of sealing at equipment connections causes fine dust to leak, which not only wastes materials but also affects workers' occupational health and environmental standards; 3) Existing systems cannot monitor internal pressure and leakage status in real time, resulting in delayed fault response and high maintenance costs.

Solutions and product advantages

Based on years of experience in sealed conveying, Head Powder has launched a customized sealed, leak-free lithium battery packing powder system. The solution uses fully welded stainless steel pipelines and patented sealed interfaces, combined with low-pressure dense phase pneumatic conveying technology, which improves conveying efficiency while minimizing leakage risks. The system is equipped with an online pressure monitoring and automatic air replenishment device, which quickly adjusts when pressure differences are detected to prevent blockage or bag rupture. Additionally, all exhaust outlets are equipped with high-precision cartridge dust collectors, ensuring emission concentrations meet the strictest local standards. The final customer's workshop achieved "zero visible dust," with material loss rates dropping from 2.8% before the renovation to below 0.1%, stable operation of the entire line, and annual maintenance time reduced by over 70%.
