Company Overview: Headpowder, whose full name is Shandong Headpowder Engineering Co., Ltd., is based in Shandong, China. The company supplied a complete dust-free pneumatic conveying system for lithium battery (LiB) powder in Trujillo, Peru. This project demonstrates a successful pneumatic conveying case in Latin America, highlighting the importance of dust-free pneumatic conveying for high-value, hazardous fine powders.

The client in Trujillo, Peru, required a safe, efficient, and dust-free method to transfer LiB powder from storage silos to processing equipment. Handling lithium battery powders such as lithium carbonate, lithium hydroxide, or cathode materials demands strict containment due to their fine particle size, chemical reactivity, and value. Manual handling or open conveying systems would lead to product loss, worker exposure, and contamination. Thus, a closed pneumatic conveying system was essential.

Headpowder engineered a pressure dilute-phase conveying system using stainless steel pipelines and welded connections to ensure zero leakage. The system operates on compressed nitrogen or dry air to maintain an inert atmosphere, preventing moisture pickup and reducing oxidation risk. The dedusting design includes a bag filter and automatic back-pressure cleaning at the receiver, ensuring that no dust escapes into the surrounding environment. This makes the facility fully compliant with international safety standards and local environmental regulations.

The dust-free pneumatic conveying system in Trujillo is composed of a rotary valve feeder, a Roots blower, a conveying pipeline with wear-resistant bends, a material receiver with reverse-jet filter, and a PLC-based control panel. The rotary valve feeds the LiB powder at a controlled rate into the gas stream. The Roots blower provides a reliable conveying velocity. The receiving hopper is equipped with a cartridge filter and pulse cleaning system, which separates solids from the gas and returns the powder to the production line without any spillage.

One of the main challenges was the abrasive nature of some LiB powders and the need to prevent metal contamination. Headpowder solved this by selecting high-grade stainless steel 304L/316L for all contact parts and applying internal surface finishing to reduce friction and material build-up. The conveying line was carefully sized to keep the product velocity within safe limits, minimizing both pipe wear and particle degradation. This attention to detail ensures consistent throughput and product quality.

The dust-free conveying solution also includes negative pressure monitoring to detect any blockages or filter failures in real time. If the system pressure rises above a set threshold, the PLC automatically adjusts the air flow or triggers an alarm. This proactive control prevents pressure shocks and keeps the operation stable. In addition, all operations are carried out in a closed loop, so dust is not emitted even during filter cleaning, thanks to the integrated dust collector and the fan recirculation design.

This project in Trujillo, Peru, is a benchmark dust-free pneumatic conveying case in Latin America. The system enables the lithium battery powder plant to run 24/7 with minimal downtime and zero environmental complaints. The plant manager reported that the system reduced material losses by nearly 100% and improved workplace safety dramatically. Moreover, energy consumption is lower than conventional mechanical conveyors because there are few moving parts and no need for extensive maintenance.

Headpowder is a leading engineering company specializing in powder conveying systems. With decades of experience in the battery materials sector, the company has delivered numerous pneumatic conveying cases across the globe. Its commitment to innovation and quality is reflected in the successful operation in Peru.
