A lithium battery material manufacturer located in Jiuquan, Gansu, involves the conveying of large amounts of ultrafine powders (such as lithium iron phosphate, ternary materials, etc.) during production. Due to their tiny particle size and large specific surface area, these powders are prone to bridging and arching in silos and pipelines, causing interruptions in conveying and affecting production line continuity. A company sought a professional solution and ultimately adopted the anti-bridge conveyor system designed by Head Powder, successfully achieving normal operation.

Customer pain point analysis

Ultra-fine lithium battery powder has poor flowability, frequently forming bridges at the silo outlet, causing poor material discharge; Traditional vibration or mechanical arch breaking methods have limited effectiveness and can easily introduce impurities or damage materials. In addition, frequent shutdowns for cleaning and maintenance have increased labor costs and equipment losses, severely limiting capacity growth. The customer urgently needed a conveying solution that could proactively prevent bridge erection from a structural design perspective while adapting to high humidity and dusty environments.

Product solutions

Head Powder customized an integrated anti-bridge pneumatic conveying system for this user: the bottom of the silo uses a special conical fluidized structure, combined with pneumatic flow support and low-frequency vibration arch-breaking devices, keeping the powder always loose; The pipeline is equipped with multi-level pressure regulation and anti-blockage monitoring, helping to prevent blockages during dense material conveyance. After the system was put into operation, the bridge erection issue was effectively controlled, equipment maintenance frequency was reduced by more than 80%, and the overall efficiency of the production line improved.

Application value

This solution not only solves common industry challenges in ultrafine powder conveying but also reduces material loss and environmental pollution through dust-free sealed conveying, helping customers achieve green production while reducing costs and increasing efficiency. Currently, this equipment has been operating normally for over two years, continuously supporting a smooth lithium battery material supply chain at the Jiuquan base in Gansu.
