In the field of powder material processing and transportation, boron nitride powder is widely used in electronics, ceramics, lubrication, and other industries due to its high thermal conductivity and chemical stability. However, boron nitride powder is prone to agglomeration during transportation, leading to reduced powder flowability, pipe blockages, and inaccurate measurement, seriously affecting production continuity and product quality. To address this industry challenge, Head Powder successfully implemented an anti-agglomeration conveying system for boron nitride powder at a project site in Ningde, Fujian, achieving stable and uniform material conveying results.

Case Summary

This case is located in Ningde, Fujian, with the client company focusing on the production and deep processing of high-performance boron nitride powder. Because boron nitride powder particles are fine and have a large specific surface area, during pneumatic or mechanical conveying, particles tend to cluster together due to van der Waals forces and static electricity, forming clumps or bridging, which reduces conveying efficiency and can even block pipelines. Customers urgently need a specialized solution that can effectively suppress agglomeration and help ensure powder conveyance continuity.

Customer pain points

• Severe reunion:Under conventional conveying methods, boron nitride powder particles adsorb together and form clumps, disrupting the original uniformity of the powder and affecting the stability of downstream mixing and molding processes.
• Low conveying efficiency:Coalescence leads to bridges erected inside the silo and blockages in pipelines, requiring frequent shutdowns for cleaning, insufficient capacity utilization, and high labor maintenance costs.
• Large mass fluctuations:Uneven powder density after agglomeration leads to performance fluctuations in subsequent batches, failing to meet the requirements for high-precision applications.

Product advantages

Head Powder, tailored to the characteristics of boron nitride powder, has optimized the conveying system structure and selected dedicated anti-agglomeration components to provide customers with customized anti-agglomeration conveying solutions.

• Anti-reunion design:Uses a low shear conveying principle combined with a special airflow distribution device to reduce particle collision and friction, suppressing agglomeration at the source.
• Stable discharge:Installing activated hoppers and arch-breaking devices eliminates bridging phenomena and helps powder enter the conveying pipeline continuously and evenly.
• Sealed and environmentally friendly:The system operates in a fully enclosed manner, equipped with efficient dust removal interfaces to prevent powder dispersion and keep the conveying environment dry, further reducing the risk of agglomeration.
• Intelligent Control:Integrated programmable controller and real-time monitoring instruments automatically adjust conveying pressure and speed to adapt to changes in powder characteristics across different batches.

After the project was put into use, the client's boron nitride powder agglomeration rate during transport dropped below 1%, the continuous operating cycle of the conveying system increased by over 200%, and product batch consistency was significantly improved, earning full recognition from the client's production department.
