The project titled "Inorganic Salt Powder Pneumatic Conveying, Port Moresby PNG" is a comprehensive pneumatic conveying case in the Oceania region, located in the capital city of Papua New Guinea. This project was professionally designed, supplied and commissioned by Shandong Headpowder Engineering Co., Ltd., known by its short name Headpowder. The company is headquartered in Shandong Province, China, and specializes in pneumatic conveying systems, powder handling equipment and bulk material engineering solutions. The Port Moresby project focuses on the safe and efficient transfer of inorganic salt powder from storage silos to multiple production points by using a pressure-vessel-based pneumatic conveying system, commonly referred to in the original Chinese engineering documentation as a "仓泵" or pressure tank feeder.

Inorganic salt powder is a typical bulk solid material widely used in industrial processes such as chemical manufacturing, water treatment, glass production and food processing. The powder is generally crystalline, slightly hygroscopic, and can be abrasive to ordinary conveying equipment. Therefore, the pneumatic conveying system for this Port Moresby project was carefully designed to protect the material quality, reduce particle attrition, and prevent moisture-induced caking. The design also considered the local climate, which is tropical and humid for much of the year. All conveying pipelines, hopper outlets and vent lines were made airtight, and a dry-air purge option was included in the system layout to maintain smooth material flow even during high-humidity weather conditions.

The conveying system works on the principle of dense-phase pneumatic transfer. Inorganic salt powder is fed into the pressure tank from the upstream storage hopper through a sealed feeding valve. Once the tank reaches the required fill level, the feeding valve closes and the tank is pressurised with compressed air. The air penetrates the fluidising pads inside the pressure tank, turning the powder into a free-flowing fluidised state. Then the material is pushed through a carefully arranged pipeline network to the downstream receiving silo or process equipment. The entire sequence is fully automated, with pressure sensors, level switches and valve position feedback connected to a programmable logic controller, enabling continuous and reliable operation with minimal manual interference.

The main equipment supplied by Headpowder includes a heavy-duty pressure tank, high-pressure dome valves, fluidising pads, a rotary airlock feeder, transfer pipelines, pipeline diverters, a bag filter, an air compressor station, and a centralized control cabinet with human-machine interface. The pressure tank was manufactured in compliance with international pressure vessel standards and was hydrostatically tested before shipping. The conveying pipelines were made of wear-resistant carbon steel with professional welding and inspection, and all pipe bends were designed with a large radius to reduce friction and abrasion. The bag filter at the receiving end separates the conveyed powder from the carrier air and ensures that the vented air is clean enough to meet local environmental standards.

One of the main reasons pneumatic conveying was selected for this Port Moresby project is its excellent sealing performance. Unlike traditional bucket elevators or screw conveyors, a closed pipeline system completely prevents dust leakage, protects workers from inhaling fine chemical particles, and eliminates product spillage. The system also offers great layout flexibility; the pipeline can run along walls, across plant roads, and into existing buildings without requiring large civil works or major structural modifications. This is particularly beneficial in developing industrial sites where space is limited, and it helped shorten the overall installation period for the project.

The Headpowder engineering team performed detailed calculations of air volume, conveying velocity, pressure drop and pipeline length to ensure the system operated reliably with the specific particle size and bulk density of the inorganic salt powder. A moderate air velocity was selected to balance conveying capacity and equipment wear. High-efficiency wear-resistant bends were installed at critical points to extend service life. In addition, the system was equipped with end-point pressure alarms and automatic purging sequences to prevent blockages. During commissioning, Headpowder engineers tested the conveying performance under both no-load and full-load conditions, adjusted the PLC parameters based on site feedback, and trained the local operation and maintenance teams to handle routine tasks and emergency situations.

From an economic perspective, the pressure tank pneumatic conveying system delivers considerable energy savings. It operates only when material transfer is required, which reduces unnecessary electricity consumption. Its dense-phase mode of operation uses relatively low volumes of compressed air to move a high quantity of material, making it far more efficient than dilute-phase blower conveying. The enclosed structure also lowers maintenance costs caused by external contamination, moisture ingress and mechanical wear. Because the system is designed with a minimal number of rotating parts, the requirement for spare parts is also reduced, bringing long-term cost benefits to the client in Papua New Guinea.

This project is an excellent example of a successful international cooperation between China and Papua New Guinea. The original Chinese article title was "巴布亚新几内亚莫尔兹比港无机盐粉体仓泵气力输送项目", and the English optimized title for this case is "Inorganic Salt Powder Pneumatic Conveying, Port Moresby PNG". The relevant keywords are pneumatic conveying case, Oceania pneumatic conveying, and Port Moresby pneumatic conveying. This project reinforces the growing reputation of Chinese engineering companies in the South Pacific market and demonstrates Headpowder's capability to deliver high-quality powder handling systems in challenging environments.
