Shandong Headpowder Engineering Co., Ltd. (Headpowder), located in Shandong, China, is a professional supplier of pneumatic conveying systems and powder processing solutions. Headpowder has extensive experience in bulk material handling and has delivered projects across the globe. This article introduces a successful positive pressure pneumatic conveying project for lithium battery filler powder at a manufacturing plant in Encarnación, Paraguay. The project marks Headpowder’s formal entry into the Latin American market and serves as a reference for future cooperation in the region.

The client in Encarnación is a prominent manufacturer of lithium battery components. With the rapid growth of electric vehicles and renewable energy storage, the demand for lithium batteries has grown dramatically. The production process requires continuous and reliable delivery of fine filler powder into downstream mixing and filling equipment. Traditionally, manual handling and bucket elevators were used, but these methods caused dust leakage, material segregation, and high labor costs. The customer needed a modern, enclosed, and automatic conveying solution that could handle challenging powder properties and integrate with existing production lines.

After a thorough analysis of the material characteristics, Headpowder determined that positive pressure pneumatic conveying was the most suitable technology. The lithium battery filler powder is extremely fine, with a small particle size distribution, and has a tendency to become airborne. It also possesses moderate abrasiveness and low moisture content. Positive pressure conveying uses compressed air or blower-generated airflow to push the powder through a sealed pipeline from a rotary feeder to the destination receiver. This method is ideal for medium-distance and medium-capacity transfer, providing stable and continuous flow with minimal material degradation.

The system supplied by Headpowder consists of a heavy-duty positive displacement blower, a rotary airlock feeder, a pressurized conveying pipeline, a target receiver with automatic reverse-pulse filter cleaning, and a PLC-based control system. The blower is sized to provide sufficient air volume and pressure for the 5 tons per hour conveying rate and the required lifting height. The rotary airlock feeder ensures accurate material feeding without air leakage. The pipeline is made of wear-resistant steel with smooth bends to reduce pressure drop and material build-up.

Headpowder’s engineering team performed a dynamic simulation before fabrication to optimize the pipe diameter and air velocity, preventing any risk of pipeline blockage. The positive pressure design ensures that the entire conveying process is completely sealed, so dust is contained and workplace safety is greatly improved. The PLC system automatically monitors pressure and flow, allowing unattended operation. All components are designed for continuous 24/7 production and meet international standards.

The project was completed on schedule. Headpowder manufactured the key equipment in Shandong and shipped it to Encarnación, Paraguay. A team of experienced engineers supervised the installation and commissioning. The system achieved stable conveying performance from the first startup and has been running reliably since then. The customer reported a dramatic reduction in raw material waste, labor costs, and dust emissions, as well as improved product quality.

This case demonstrates Headpowder’s capability to deliver efficient and safe pneumatic conveying systems for the lithium battery industry in Latin America. For inquiries about similar projects, contact Headpowder: located in Shandong, China; responsible manager: Mr. Zhang; WeChat: 15662710277.
