The project titled "Anti-CakingPneumaticConveyingofBoronNitrideinDammam" (in standard English, "Anti-Caking Pneumatic Conveying of Boron Nitride in Dammam") is a successful pneumatic conveying case implemented by Shandong Headpowder Engineering Co., Ltd. (headpowder), located in Shandong, China. This project was carried out in Dammam, Saudi Arabia, to convey ultra-fine boron nitride powder through a sealed pipeline while effectively preventing agglomeration. It is a representative Middle East pneumatic conveying application, demonstrating how advanced engineering can solve the challenging problem of handling cohesive superfine powders in a hot, humid and harsh desert environment. Headpowder's expertise in anti-caking technology makes this project a benchmark for similar applications worldwide.

Boron nitride ultra-fine powder is known for its strong agglomeration tendencies due to its very small particle size, high specific surface area and intense van der Waals forces. In Dammam's coastal climate, atmospheric moisture can easily be adsorbed onto the powder surface, making the material more cohesive and difficult to transport. Under conventional pneumatic conveying, high air velocities and turbulent flows generate electrostatic charges and increase particle-to-particle and particle-to-wall collisions, which further promote the formation of lumps and result in pipeline blockages. These problems can lead to expensive shutdowns, product contamination and safety hazards. Therefore, a specialized anti-caking approach is essential for the reliable transport of this material.

Headpowder designed a custom dense-phase pneumatic conveying system that operates at lower gas velocities and with a carefully controlled solid-to-gas ratio. The system uses dry and inert gas, such as nitrogen, as the conveying medium to prevent any chemical reaction or moisture pickup. A dehumidification unit ensures that the gas humidity stays below the critical level. At the feed point, a special dispersing device breaks apart initial agglomerates and uniformly mixes the powder with the gas stream. The pipeline is manufactured from high-polish stainless steel with a mirror finish and is laid out without sharp bends or dead zones to minimise adhesion and flow resistance. Real-time pressure sensors, flow meters and humidity probes send data to a PLC-based controller, which automatically adjusts the conveying velocity and gas pressure. If any material buildup is detected, the system sends a high-pressure pulse to clear the line before a blockage can develop.

This Middle East pneumatic conveying project is an excellent example of how anti-caking technology can be adapted to extreme climates. Dammam experiences high temperatures, high humidity and frequent sandstorms, all of which place additional demands on machinery. To cope with these conditions, all electrical enclosures were designed with high ingress protection ratings, and the control panels were placed in air-conditioned rooms. The project also included training for local operators and a complete maintenance manual, enabling the client's team to keep the system running smoothly. After successful commissioning, the client was highly satisfied and has ordered additional conveying lines for other powders. This positive outcome confirms headpowder's reputation as a reliable partner for powder handling projects in the Middle East and beyond.
