A new energy materials company faced severe challenges of iron pollution during powder transportation when building a high-purity powder production line in Nantong, Jiangsu. The purity of high-purity alumina powder produced by this company is required to reach over 99.99%. Any trace amount of iron impurities can lead to product quality degradation or even scrapping. Head Powder has tailored a high-purity powder iron-free transport project for them, achieving full-process iron-free transformation from equipment selection to system integration, helping powder purity remain unaffected during transportation.

Customer pain points

In traditional pneumatic conveying systems, metal components such as pipelines, valves, and elbows are prone to iron filings falling off due to wear and corrosion during long-term operation; At the same time, the metal contact surfaces inside the conveying equipment also release trace amounts of iron ions under high-speed airflow scouring. These issues have caused the iron content in the powder to rise from less than 0.1 ppm at the raw material end to over 1 ppm at the finished product end, which is far from meeting the stringent iron impurity content requirements of specialized industries such as electronic ceramics and lithium battery cathode materials. In addition, the existing equipment frequently stops to clean iron filings, seriously affecting production efficiency and batch stability.

Product advantages

Head Powder addresses these pain points by providing solutions from three dimensions: material selection, structural design, and system sealing. All conveyor pipelines and key components are lined with 304 stainless steel with high-polymer wear-resistant ceramic or pure PTFE material, fully isolating iron from contact; Independently developed no-dead angle elbow design reduces powder retention and friction; The fully enclosed negative pressure conveying system is equipped with a magnetic separative iron filtration device, achieving zero iron pollution during the conveying process. Actual operational data show that the project can control the incremental amount of finished iron powder within 0.02 ppm, without the need for additional downtime and cleaning, and the continuous operating cycle has increased by more than 300%.
