To meet the clean powder conveying needs of a dye manufacturer in Chenzhou, Hunan, Head Powder provided a customized pneumatic conveying system that addressed cross-contamination issues during production and supported high purity and process stability of powder materials.

Case Summary

The company has long been engaged in the production and processing of dye powders, and faces serious cross-contamination risks during powder transfer, feeding, and transportation, which not only affects product quality but also reduces batch stability, increasing rework and scrap costs.

Customer pain points

There are many types of dye powders, with fine particle sizes and easy adsorption. Traditional mechanical conveying methods (such as screw and bucket lifting) have issues such as insufficient removal of residual materials, pipeline accumulation, and mixing of powders of different colors or compositions. In addition, workshops require high cleanliness and involve many manual operations, making it difficult to control dust escape, posing threats to the working environment and personnel health.

Product advantages

To address these pain points, Head Powder has designed a fully enclosed pneumatic conveying system, achieving cleanliness without cross-contamination through the following solution:

• Modular pipeline components and quick-open cleaning interfaces support periodic segmented cleaning, eliminating material residues.
• Equipped with high-efficiency filtration and pulse back-blowing devices, it helps clean the delivered gas and prevents secondary pollution.
• The system operates in a completely enclosed manner, with no dust escaping, meeting the cleanroom grade requirements.
• Automated control can accurately switch between different material conveying paths, enabling rapid production switching of multiple varieties without mixing risks.

This solution has been successfully applied at the Chenzhou project site in Hunan, reducing cross-contamination rates and improving product qualification rates and production efficiency.
