Head Powder designed and implemented a dilute-phase anti-fly material conveying project for lithium battery powder for a lithium battery materials company in Guang'an, Sichuan, improving dust and loss issues during powder transportation.

Case Summary

This lithium battery company is located in Guang'an, Sichuan, mainly producing lithium battery cathode and anode materials. The powder has fine particle size and low density, and it faces serious flying material and environmental pollution in traditional transportation processes. Based on on-site process conditions, Head Powder has customized a set of rare phase pneumatic conveying systems, achieving fully sealed, low-air, and high-precision conveying from feeding to storage.

Customer pain points

The original conveying method used open or semi-enclosed equipment, which had the following prominent issues:

• Severe dust generation leads to material waste and pollution of the workshop environment;
• Lithium battery powder is sensitive to impurities, and open conveying easily mixes in foreign matter, affecting product quality;
• Traditional positive pressure conveying has high wind speeds, significant pipeline wear, and persistently high maintenance costs;
• Without real-time monitoring, the conveying process cannot be accurately controlled, making it difficult to troubleshoot when pipe blockages occur.

Product advantages

The dilute phase anti-fly material conveying system launched by Head Powder has been specially optimized to address these pain points:

• Fully enclosed pipeline design:Uses airtight flange connections, combined with negative pressure or low-pressure dilute phase conveying, preventing dust leakage at the source, and increasing material recovery rates to over 99%;
• Low wind speed, low wear:The conveying air velocity is controlled within the range of 12~18m/s, resulting in minimal collision force between materials and the inner wall of the pipeline, effectively extending equipment lifespan and reducing powder breakage;
• Anti-static and moisture-proof treatment:The inner walls of the pipes are coated with anti-static coatings and equipped with dehumidification devices to meet the strict requirements for static electricity and humidity in lithium battery powders;
• Intelligent Control System:Integrated PLC and host computer to monitor conveying pressure, flow, and material level in real time, automatically adjust air source and feed volume, and provide timely alarms in case of abnormalities, reducing manual intervention.

After the project was put into operation, the workshop's dust concentration dropped below the national standard limit, material loss decreased by about 8%, and the conveying system operated continuously for 12 months without pipe blockage incidents, earning high recognition from customers.
