Dust-Free Vacuum Conveying of Lithium Carbonate, Lae PNG — A Successful Pneumatic Conveying Case in Oceania. Keywords: pneumatic conveying case, Oceania pneumatic conveying, lithium carbonate pneumatic conveying. This article covers a lithium carbonate conveying project completed by Shandong Headpowder Engineering Co., Ltd. in Lae, Papua New Guinea. The system applies vacuum suction to transfer lithium carbonate powder through a fully sealed pipeline, achieving a dust-free, efficient and reliable material handling solution for the local processing plant.

Lae is the main industrial port and the second largest city of Papua New Guinea, situated on the country's northern coast. It is a central hub for shipping, logistics and manufacturing, and it connects the island nation to international markets. As regional demand for lithium battery materials grows, plants in Lae are modernizing their powder handling capabilities. This newly installed vacuum conveying line helps the customer improve product consistency, reduce waste and protect workers from dust exposure.

Lithium carbonate is a fine white powder used as the main precursor for cathode materials in lithium-ion batteries. It has demanding purity requirements and can be difficult to handle because it is sensitive to moisture, easily airborne, and prone to bridging or sticking inside ordinary transfer equipment. Any dust escaping from the process can create housekeeping problems and health risks. The negative-pressure conveying approach solves these issues by keeping the material completely enclosed from the feed point to the final destination.

The system delivered for the Lae project includes a vacuum pump, suction probes, a wear-resistant pipeline, a receiving vessel, a filter separator with pulse-jet cleaning, and a rotary airlock discharge valve. During operation, the suction generated by the vacuum pump makes the lithium carbonate powder flow through the pipeline at a controlled velocity. The filter separates the powder from the conveying air, and the rotary valve releases the collected material into the downstream process without permitting outside air to enter. The entire sequence is managed by a PLC-based control unit with a user-friendly touch screen.

Because the conveying line runs at negative pressure, all flanges and connections remain under suction, which ensures that dust always moves inward rather than escaping into the work area. This sealed design provides excellent environmental protection and meets the high occupational safety requirements of modern battery material plants. It also reduces material loss and keeps the surrounding equipment clean.

The system also improves productivity by allowing operators to adjust the feed rate precisely, respond quickly to process changes, and monitor the conveying status in real time. The PLC records key parameters such as pressure, airflow and filter condition, and it alerts the operator when maintenance is needed. This reduces unplanned downtime, ensures batch-to-batch consistency, and gives the Lae plant a higher degree of automation in its daily production.
