Guangdong Dongguan Conductive Carbon Black Lithium Feeding Project

Project Introduction

A lithium battery material manufacturer in Dongguan, Guangdong, faced persistent challenges in its conductive carbon black feeding process. The company, referred to as Company H, required a reliable and efficient solution to handle fine, low-density conductive carbon black powder for lithium-ion battery electrode production.

Customer Pain Points

The existing manual feeding method caused severe dust pollution, leading to workplace safety concerns and material waste. Inconsistent feeding rates resulted in variations in product conductivity, affecting battery performance. The fine carbon black particles also tended to agglomerate, causing blockages and downtime. High labor intensity and frequent equipment cleaning further reduced overall production efficiency.

Solution & Product Advantages

Headpowder designed and implemented a fully automated pneumatic conveying and feeding system tailored for conductive carbon black. The solution integrated a negative pressure dense phase conveying system to minimize dust emission and maintain material integrity. A precision loss-in-weight feeder ensured consistent, programmable feeding rates within ±0.5% accuracy. An anti-bridging hopper with active vibration prevented material clogging, while an enclosed pipeline system eliminated contamination risks. The entire process was controlled by a PLC with HMI interface, allowing remote monitoring and parameter adjustment.

As a result, Company H achieved a 95% reduction in dust leakage, eliminated manual intervention, and improved feeding consistency by 30%. Equipment maintenance intervals extended from weekly to quarterly, and overall production throughput increased by 40%.
