Shandong Headpowder Engineering Co., Ltd. (headpowder) has completed a dense phase pneumatic conveying project for PVC resin powder in Oslo, Norway. This case highlights the company’s capability in designing advanced conveying systems for the European market. The client required a safe, efficient, and dust-free solution to transfer PVC powder from storage to processing equipment while maintaining product quality. The successful execution of this project further strengthened headpowder’s reputation in European pneumatic conveying applications.

PVC resin powder is fine, light, and sensitive to mechanical impact. Traditional dilute phase conveying uses high air velocity, which can cause particle degradation and severe pipe wear. To solve this problem, headpowder adopted dense phase conveying technology. In this system, the powder is moved as plugs at low velocity under high pressure, ensuring gentle handling and minimal breakage. This technology is particularly suitable for PVC resin, which requires careful handling to avoid the generation of fines and dust.

The complete system includes a pressure vessel, screw compressor, conveying pipeline, special discharge valves, and a PLC-based control unit. The material is loaded into the pressure vessel, then fluidized by compressed air. When the vessel reaches the set pressure, the discharge valve opens and the powder is pushed through the pipeline in a dense phase plug. The PLC automatically controls each batch cycle, including loading, pressurization, conveying, and line purging. The system is designed for fully automatic operation with remote monitoring capability.

At the receiving end, a cyclone separator and a bag filter separate the PVC powder from the conveying air. The closed-loop design prevents any dust emission, meeting strict environmental regulations in Oslo. The system also incorporates nitrogen purge for explosion safety and a desiccant dryer to avoid moisture absorption. These features are essential for reliable operation in Norway’s climate.

This project was designed for a conveying capacity of 12 tons per hour over a distance of 180 meters, with a vertical lift of 25 meters. The operating pressure is 2.5 bar, and the conveying velocity is controlled between 2 and 5 m/s. Compared with conventional dilute phase conveying, this dense phase system reduces energy consumption by about 30% and significantly extends the lifetime of pipes and bends. This results in lower operating costs and a shorter payback period for the customer.

Headpowder supplied all engineering documents, including P&ID, GA drawings, and operation manuals, in compliance with CE and ATEX directives. Engineers from headpowder supervised the installation and commissioning in Oslo. The system completed trial operation successfully, meeting every performance specification and gaining high acceptance from the client. All site work was carried out according to Norwegian safety codes and project schedules.
