H3: Vietnam Quang Ngai Boron Nitride Powder Anti-Agglomeration Conveying Case Study
This article presents a practical pneumatic conveying case study from Quang Ngai, Vietnam, focusing on the anti-agglomeration handling of boron nitride powder. The project was successfully delivered by Shandong Headpowder Engineering Co., Ltd., a leading provider of customized pneumatic conveying systems. The solution effectively addressed the unique challenges posed by boron nitride powder, which is known for its low bulk density, high specific surface area, and strong tendency to agglomerate under normal conveying conditions. By integrating advanced anti-agglomeration technologies, the system ensured stable, continuous, and contamination-free transport of the material from storage to downstream processing equipment.
H3: Challenges in Boron Nitride Powder Pneumatic Conveying
Boron nitride powder, widely used in the electronics, ceramics, and lubricant industries, presents significant difficulties in pneumatic conveying. Its fine particle size, often below 10 microns, combined with a high aspect ratio, causes the powder to easily form stable agglomerates due to van der Waals forces and electrostatic charges. In conventional dilute-phase conveying systems, the high air velocity and turbulence can actually worsen agglomeration, leading to blockages, inconsistent flow, and product quality degradation. Moreover, the material is highly abrasive and sensitive to contamination, requiring careful selection of pipeline materials and sealing mechanisms. In the Quang Ngai facility, the client needed a system that could handle a throughput of 500 kg/h while maintaining a consistent particle size distribution without any caking or bridging. The existing mechanical conveying methods had resulted in frequent downtime and excessive maintenance, making a shift to pneumatic conveying with anti-agglomeration features urgent.
H3: Anti-Agglomeration Pneumatic Conveying Solution
To overcome these challenges, the Headpowder engineering team designed a dense-phase pneumatic conveying system specifically tailored for boron nitride powder. The core of the solution is a patented anti-agglomeration technology that uses controlled low-velocity air injection combined with a specialized feeding device. Unlike traditional venturi or rotary airlock feeders, the system employs a gentle fluidization bed at the pickup point, which breaks down initial agglomerates without causing particle attrition. The conveying pipeline is equipped with periodic air boosters that maintain a stable plug flow, preventing the powder from compacting and forming solid lumps. Additionally, the system incorporates a proprietary coating treatment on the inner pipe surface to reduce friction and electrostatic buildup, which further minimizes the risk of re-agglomeration. The entire process is monitored by real-time pressure sensors and flow meters, ensuring that the conveying velocity remains within the optimal range of 3-8 m/s. This anti-agglomeration pneumatic conveying approach has been validated in multiple laboratory and field tests, and the Quang Ngai project was the first large-scale implementation in Vietnam.
H3: Project Implementation in Quang Ngai, Vietnam
The project site is located in the Quang Ngai province of Vietnam, a region that has seen rapid industrial growth in the advanced materials sector. The client, a major manufacturer of boron nitride-based thermal management materials, required a reliable and efficient conveying system to feed their mixing and granulation units. The system was designed to handle both raw boron nitride powder and a pre-blended mixture with additives, which further complicated the flow behavior. Headpowder's team conducted a thorough site survey and material characterization, including particle size analysis, bulk density measurement, and moisture content evaluation. Based on these data, the system was engineered with a 4-inch diameter stainless steel pipeline, a total length of 120 meters, and 8 directional changes. Special attention was paid to the bend radius, using large-radius elbows (R=10D) to minimize pressure drop and particle degradation. The installation was completed within 6 weeks, and the commissioning phase included a 72-hour continuous operation test. The results showed that the anti-agglomeration pneumatic conveying system achieved a stable conveying rate of 520 kg/h with a variation of less than 3%, and no agglomerates larger than 50 microns were detected in the downstream product. The Quang Ngai case study has since become a reference for other boron nitride powder handling projects in Southeast Asia.
