In recent years, with the rapid development of the new energy industry, lithium salt powder, as a key material for lithium batteries, has received increasing attention regarding its safety and environmental protection during production and transportation. At a large lithium salt processing base in Hanzhong, Shaanxi, Head Powder undertook an anti-static sealed conveying project for lithium salt powder. Through systematic solutions, it improved safety hazards and material loss issues in traditional powder conveying processes.

Project Background and Customer Challenges

This customer mainly produces various lithium salt powder products and faces multiple challenges in powder transportation and feeding. Lithium salt powder carries a risk of static electricity accumulation and is prone to ignition and explosion accidents caused by static discharge in open environments; At the same time, the powder is highly fine and viscous, making it prone to blockages and dust during transportation, leading to material waste and environmental pollution. In addition, the production line has strict requirements for conveying efficiency and airtightness, and existing equipment cannot meet the stability needs of continuous all-weather operation.

Core pain point analysis

The client clearly identified the following key pain points during project initiation: First, static electricity prevention and control are difficult; traditional metal pipes and ordinary plastic pipes cannot effectively conduct static electricity; Second, the conveying system lacks sealing and causes severe powder leakage, causing not only economic losses but also affecting workers' health; Third, low level of automation, frequent manual intervention, and inability to accurately control the ratio of conveyed volume to batch; Fourth, the equipment lacks sufficient corrosion resistance; lithium salt powder corrodes the pipeline material and shortens the equipment's service life.

Solutions and product advantages

To address these pain points, Head Powder offers a customized anti-static sealed conveying system. This system adopts multiple anti-static designs, with conductive layers embedded on the inner walls of pipes and reliable grounding to help dissipate static electricity in a timely manner; The entire conveying line adopts a fully enclosed structure, combined with negative or positive pressure pneumatic conveying technology to prevent powder spillage; The system integrates an intelligent control module that can monitor conveying pressure, flow, and temperature in real time, supporting remote operation and fault warning; At the same time, pipelines and valves are made of corrosion-resistant alloys or lined with Teflon materials to extend the service life of equipment in corrosive environments.

Through this project, the customer achieved safe and controllable powder conveying processes, reduced material loss rates by over 90%, reduced dust concentration in the working environment below national emission standards, and maintained stable and reliable equipment operation, laying a solid foundation for subsequent capacity improvement.
