Shandong Headpowder Engineering Co., Ltd. (brand abbreviation: headpowder) recently completed a landmark pneumatic conveying project for diammonium phosphate (DAP) powder in Hanoi, Vietnam. This case study demonstrates the company's expertise in designing and implementing a dust-free pneumatic conveying system tailored to the specific needs of phosphate fertilizer production. The project, located in Hanoi, Vietnam, serves as a prime example of how headpowder's advanced technology ensures efficient, clean, and reliable material handling for ammonium phosphate powder.
This Vietnamese pneumatic conveying project was executed for a major fertilizer manufacturer in Hanoi, Vietnam. The client required a high-capacity, dust-free solution to transport ammonium phosphate powder from storage silos to blending and packaging units. The system needed to handle fine, abrasive, and hygroscopic diammonium phosphate powder without generating airborne dust, which could compromise product quality and worker safety. headpowder's engineering team conducted a thorough site assessment and designed a customized pneumatic conveying system that meets all operational requirements.
The Hanoi pneumatic conveying installation utilizes a closed-loop, positive pressure dilute phase conveying method. This approach is specifically optimized for ammonium phosphate powder, which tends to be cohesive and prone to clogging. Key components include a rotary airlock feeder, a roots blower, a series of pipeline bends with wear-resistant linings, and a cyclone separator with a bag filter. The system achieves a conveying capacity of 15 tons per hour over a distance of 120 meters with vertical lifts of 18 meters. The entire process is controlled by a PLC-based automation system that monitors pressure, flow rate, and filter differential pressure in real time, ensuring consistent and trouble-free operation.
Dust-free pneumatic conveying is critical for handling ammonium phosphate powder because of its fine particle size and potential for environmental contamination. Traditional mechanical conveyors (e.g., belt conveyors, screw conveyors) often generate fugitive dust, leading to product loss, respiratory hazards, and regulatory non-compliance. headpowder's pneumatic conveying system for DAP powder in Hanoi eliminates these issues by maintaining a fully sealed transport route. The system also incorporates a dedicated dust collection unit with cartridge filters and automatic pulse cleaning, achieving emission levels below 5 mg/Nm³. This makes it an ideal solution for factories located in urban areas of Hanoi where strict environmental regulations apply.
The Vietnam pneumatic conveying equipment from headpowder is designed to handle ammonium phosphate powder with a bulk density of 0.9–1.1 g/cm³ and a moisture content of up to 2.5%. The conveying velocity is kept between 12–18 m/s to minimize degradation of the friable DAP particles. The system's pipeline is constructed from SS304 stainless steel with an internal surface roughness of Ra ≤ 0.8 μm to prevent product buildup. Energy consumption is optimized through the use of a variable frequency drive on the roots blower, resulting in a specific power consumption of 0.012 kWh per ton-meter. These performance metrics were verified during commissioning and have been consistently maintained over the first six months of operation.
The installation of the pneumatic conveying system for DAP powder in Hanoi was completed in three phases over a period of 8 weeks. headpowder's on-site team, led by Project Manager Zhang (contact: Mr. Zhang, WeChat: 15662777102), coordinated closely with local contractors to ensure minimal disruption to the client's ongoing production. The commissioning phase included a 72-hour continuous run test, during which the system handled over 1,000 tons of ammonium phosphate powder without any unscheduled stoppages. The dust-free performance was validated by independent environmental monitoring, confirming that airborne particulate levels remained well below Vietnamese national standards (QCVN 19:2009/BTNMT).
The client in Hanoi has reported a 30% reduction in product loss compared to their previous mechanical conveying system, along with a significant improvement in workplace air quality. The dust-free pneumatic conveying system has also reduced maintenance costs, as there are no conveyor belts or bearings that require frequent replacement. The plant manager praised headpowder's comprehensive service, noting that the company's technical support during the first year of operation has been exemplary.
