At a certain lithium battery ceramic material production base, the high-purity powder transportation stage has long faced challenges of cross-contamination and material loss. Traditional mechanical conveying methods not only fail to improve powder purity, but also cause excessive dust levels in production environments due to equipment wear and poor sealing. Head Powder has provided a fully sealed, pollution-free pneumatic conveying system for this scenario, addressing both material purity and environmental protection requirements from the source.

Customer pain points

High-purity lithium battery ceramic powder is extremely sensitive to impurity content; any trace amount of metal foreign matter or environmental dust mixed in will affect the insulation performance and thermal stability of the ceramic substrate. The original conveying method had three major drawbacks: first, open conveying caused secondary air dust pollution; second, mechanical contact parts wear and metal debris; Third, material residues cause cross-contamination between batches. In addition, production lines are noisy and consume high energy, making it difficult to meet increasingly stringent environmental emission standards.

Product advantages

Head Powder's pollution-free conveying solution uses low-flow dense-phase pneumatic conveying as its main technology, combined with all-stainless steel pipelines and food-grade seals, to ensure smooth material flow within enclosed pipelines, avoiding particle crushing and pipeline wear. The system is equipped with an automatic back-blowing cleaning device to prevent the accumulation of residual materials; Real-time pressure monitoring and intelligent control modules can automatically adjust the gas-solid ratio according to material characteristics, improving conveying efficiency to a high level while supporting pollution-free operations. The entire plan is compactly laid out, adapting to the existing factory space at the Jiujiang site, without the need for large-scale civil engineering renovations.

Project Results

After the project was implemented, impurity content detection in the powder conveying stage stabilized below 0.1 ppm, workshop dust emission concentrations dropped to less than one-tenth of the national standard limit, and material loss rates decreased from the original 1.5% to within 0.2%. Customer feedback states that this solution not only solves long-standing production quality issues, but also reduces the frequency of downtime and cleaning, saving about 400,000 yuan in annual maintenance costs. Through this case, Head Powder further validated its technical adaptability and engineering delivery capability in the field of lithium battery ceramic high-purity powder transportation.
