This is a successful inert gas pneumatic conveying project for silicon-carbon anode powder in Trondheim, Norway. It is an important European pneumatic conveying case and demonstrates headpowder's ability to handle oxygen- and moisture-sensitive battery materials through a fully closed inert gas conveying system.

Silicon-carbon anode powder is a high-capacity active material for lithium-ion batteries, but its silicon content is chemically reactive. Exposure to oxygen or humidity causes oxidation, moisture pickup, and a loss of electrochemical performance. The ultra-fine powder is also easy to fluidize and can create harmful dust. For these reasons, open conveying equipment is not acceptable, and the material must be transported in a dry, oxygen-free atmosphere.

Headpowder, short for Shandong Headpowder Engineering Co., Ltd., designed a closed-loop nitrogen pneumatic conveying system for the Trondheim site. Nitrogen is continuously recirculated in the line and maintains a slight positive pressure, so ambient air cannot enter. Oxygen analyzers, pressure sensors, moisture probes, and fine filters are installed at critical points. This ensures that the silicon-carbon anode powder remains protected from oxidation and moisture throughout the whole conveying process.

The dense-phase system uses low gas velocity and high solid-to-gas ratio, reducing collision, attrition, pipe wear, and heat build-up while preserving particle morphology. Equipment includes receiving silos, valves, pressure vessels, stainless steel pipelines, gas recirculation filters, and PLC-based controls. Operators monitor pressure, temperature, oxygen content, and line status in real time.

Safety and compliance with European standards were vital for this project. The engineering design follows the European Machinery Directive and ATEX requirements, including hazardous zone classification, explosion protection, electrical grounding, and safe purging. The successful execution in Trondheim proves that headpowder can cooperate smoothly with European contractors and end users and can deliver systems that meet local safety and quality demands.

For the client, the key advantages are no oxidation, no moisture absorption, no dust emission, and low product loss. A regeneration unit recovers the conveying gas and returns it to the pipeline, reducing operating cost. Headpowder provided engineering, manufacturing, installation supervision, commissioning, training, and after-sales support.

This Trondheim project is a typical European pneumatic conveying case and a strong example of inert gas protective pneumatic conveying. It also strengthens headpowder's track record in advanced battery materials. Since headpowder is headquartered in Shandong, China, and serves customers both at home and abroad, the successful Norwegian project will support further expansion in the European market.

In summary, the Norwegian Trondheim silicon-carbon anode powder inert gas pneumatic conveying project successfully solves the key problems of oxidation, moisture adsorption, dust pollution, and particle breakage. It maintains the original quality of the silicon-carbon anode powder, supports reliable production of lithium-ion battery materials, and provides a valuable reference for other plants handling fine, reactive, or moisture-sensitive powders in a totally closed and inert environment.
