PlasticPowderPneumaticConveyinginJeddah,SaudiArabia is an outstanding case study from Shandong Headpowder Engineering Co., Ltd. This project demonstrates how a pressure vessel (also known as “仓泵” in Chinese) pneumatic conveying system can efficiently and safely transport plastic powder in one of the most active industrial cities of the Middle East. The successful execution of this project reinforces Headpowder’s position as a leading supplier in the Middle East pneumatic conveying market. The Jeddah installation has become a significant reference for plants that require dust-free, long-distance, and low-energy powder transfer solutions.

Headpowder, short for Shandong Headpowder Engineering Co., Ltd., is headquartered in Shandong, China. The company designs, manufactures, and installs pneumatic conveying systems, including dense-phase pressure vessel conveyors, positive pressure systems, vacuum conveying systems, and complete powder handling solutions. With decades of experience, Headpowder serves the plastic, chemical, mineral, and food industries worldwide. The engineering team specializes in developing tailor-made solutions that account for each material’s unique flow characteristics, the site layout, and the customer’s production capacity requirements.

The client in Jeddah, Saudi Arabia, operates a plastic powder processing plant that required a reliable and clean method to transfer plastic powder from a central storage silo to multiple processing lines. Previously, the plant used manual bins and mechanical conveyors, which led to dust leakage, material loss, and inconsistent feed rates. In addition, the existing layout made it difficult to install a conventional screw conveyor. To solve this problem, the client sought a pneumatic conveying solution that would be dust-tight, flexible in routing, and low in maintenance. Headpowder proposed a pressure vessel pneumatic conveying system, which fully met all of these requirements.

The plastic powder handled at the Jeddah plant has a bulk density in the range of 400 to 600 kg/m³, with an average particle size of approximately 200 microns. This material is free-flowing when dry, but it can generate significant dust when disturbed. Furthermore, certain plastic powders are combustible, and strict safety measures must be implemented during conveying. Because of these characteristics, a dense-phase pressure vessel conveying system was selected over dilute-phase conveying. Dense-phase conveying operates with a high solid-to-air ratio and a low air velocity, which minimizes dust generation and particle degradation while protecting the pipeline from severe wear.

This pneumatic conveying case study focuses on the design of a dense-phase system using a pressure vessel. The system uses compressed air to force the plastic powder through a sealed pipeline in the form of slugs or plugs. Such a mode of transport is ideal for plastic powder because it keeps the material moving gently yet reliably. The conveying distance in the Jeddah plant is about 120 meters, and the design capacity is 5 tons per hour. The pipeline route was carefully designed to avoid excessive vertical lifts and sharp bends, ensuring smooth flow and low energy consumption. A dedicated air compressor was installed to provide the necessary pressure and flow rate.

The main components of the pressure vessel conveying system include a feed hopper, an inlet valve, a pressure vessel (also called a discharge vessel), a discharge valve, a conveying pipeline, a receiving bin, a filter receiver, an air compressor, and a PLC control cabinet. The operation cycle is fully automatic: first, the plastic powder is fed into the pressure vessel from the hopper; then the inlet valve closes, and compressed air is introduced into the vessel. When the pressure reaches the set value, the discharge valve opens, and the material is conveyed through the pipeline to the receiving bin. Once the vessel is empty, the pressure is vented, and the next cycle begins automatically.

Headpowder engineers calculated the exact air velocity, pressure, and air-to-material ratio based on the particle size, bulk density, and moisture content of the plastic powder. For the Jeddah project, all material contact parts were fabricated from stainless steel 304 to prevent any contamination. The system is also equipped with explosion-proof venting, grounding, and antistatic measures because plastic powder can form explosive dust clouds under certain conditions. The PLC control system continuously monitors vessel pressure, material level, and valve status, while a touch screen interface provides operators with real-time data, alarms, and historical trends. This level of automation greatly reduces manual intervention and ensures repeatable performance.

The installation of this pressure vessel pneumatic conveying system brought several important benefits to the Jeddah plant. Dust emission was completely eliminated because the entire conveying line is sealed, resulting in a cleaner and safer working environment. The accurate PLC control ensures a stable feeding rate, improving the consistency and quality of the final plastic products. The low-velocity dense-phase transport also reduced maintenance downtime and energy costs when compared to previous mechanical handling methods. The client reported that the system operates smoothly even under continuous production schedules and requires minimal routine maintenance.

Headpowder provided a complete turnkey service for this project, from the initial site survey and pipe layout design to equipment manufacturing, installation, commissioning, and operator training. The project was completed within the agreed schedule, and no major issues were reported during the first year of operation. This successful project in Jeddah is now a reference for other plastic powder manufacturers in Saudi Arabia and the wider GCC region. It demonstrates the reliability and technical expertise of Headpowder in executing international projects under demanding environmental and safety standards.
