Case study of nitrogen protective transport for lithium battery anode powder in Chengde, Hebei
In the production process of lithium battery anode materials, the powder conveying stage is directly related to product quality and production safety. A company specializing in lithium battery anode materials in Chengde, Hebei, faces challenges in powder transportation, including high oxidation risks, severe dust dispersion, and significant material loss. Head Powder customized a nitrogen protection conveying system for them, addressing these challenges.
Customer pain points

The company's original pneumatic conveying system used air as the transport medium, causing the anode powder to come into contact with oxygen during transport, resulting in surface oxidation and affecting battery material performance; At the same time, the open system generates fine dust, which not only pollutes the workshop environment but also increases material waste and subsequent processing costs. In addition, traditional conveying methods cannot accurately control flow rates, resulting in insufficient production stability.
Head Powder Solutions

Head Powder uses a fully sealed nitrogen protection pneumatic conveying system tailored to customers' actual working conditions. The system uses high-purity nitrogen instead of air as the power medium, isolating oxygen at the source, which helps the powder remain protected by inert gases throughout transport, effectively preventing oxidation and deterioration. The pipeline features wear-resistant and sealed designs, equipped with intelligent pressure monitoring and automatic nitrogen replenishment devices to maintain micro positive pressure within the system and prevent external air from seeping in. At the same time, an automated control system is integrated to achieve more accurate feeding, flow regulation, and remote monitoring, thereby improving production continuity and stability. After the upgrade, the oxidation rate of materials was reduced to negligible levels, dust emissions were nearly zero, and annual material loss and treatment costs saved exceeded expectations.
Application value

This case fully validates the adaptability and reliability of nitrogen protection conveying systems in the field of lithium battery anode materials. Through targeted design, Head Powder helps customers achieve multiple goals of clean production, quality improvement, cost reduction, and efficiency enhancement, providing replicable technical pathways for similar enterprises.
