The Bogota project undertaken by Headpowder (Shandong Headpowder Engineering Co., Ltd.) demonstrates excellence in designing and delivering a fully enclosed pneumatic conveying system specifically for lithium battery powder. Located in the capital of Colombia, this installation serves a leading battery materials manufacturer that requires precise, contamination-free transfer of fine cathode and anode powders. Our team was engaged to provide a complete solution from the earliest feasibility study through to final commissioning.

The system uses dilute-phase pressure conveying with a closed feed vessel, which allows batches of powder to be introduced into the pipeline without opening the process. This closed-feed concept is essential for lithium battery materials because even tiny leaks can cause product oxidation, moisture uptake, or safety hazards. By using a sealed hopper and a series of automated valves, the powder is safely discharged into a pressurized nitrogen stream and transported over a distance of 80 meters to four different receiving hoppers. The entire transfer process operates under a controlled atmosphere, ensuring stability and quality of the end product.

One of the most challenging aspects of this project was the high-altitude location of Bogota, which sits at approximately 2,640 meters above sea level. At this elevation, air density is lower, which affects the velocity and pressure profiles of the conveying gas. Headpowder’s engineering team performed accurate thermodynamic calculations to compensate for the reduced atmospheric pressure. We selected a high-capacity Roots blower with a frequency converter, adjusted the pipe diameter from the standard 108 mm to 125 mm, and optimized the pick-up velocity from 25 m/s to 22 m/s. These modifications guaranteed a smooth and stable flow of lithium battery powder without pipe blockage or sedimentation.

Safety is a top priority in any lithium battery powder application. The Bogota system includes explosion-relief panels, oxygen analyzers, and interlocking valves. Made of stainless steel 304 with a surface roughness of Ra≤0.4 μm, the piping prevents adhesion and simplifies cleaning. All electrical components are hazardous-rated, and the control cabinet is purged with instrument air. The nitrogen supply is filtered and continuously monitored for dew point to keep it absolutely dry.

The PLC-based control panel with a touchscreen provides real-time monitoring of pressure, flow, and filter differential pressure. Alarm logs and trends are stored for maintenance planning. The system runs in automatic or manual mode for flexible startup and cleaning. Wear-resistant fittings at elbows reduce downtime. Receiving hoppers use high-efficiency cartridge filters, and nitrogen is recycled for gas economy. This closed loop also reduces operating costs and environmental impact.

Since start-up, the system has achieved a conveying capacity of 2.5 tons per hour with a powder-to-air ratio of 8:1. It handles particle sizes from 5 to 30 microns and bulk densities of 0.4 to 1.2 g/cm³. Extensive testing with the customer’s actual powder samples was conducted in Headpowder’s test laboratory before finalizing the design. Testing confirmed that closed-feed conveying reduces degradation by 30% versus open conveyors and eliminates dust emissions.

The Bogota project has made Headpowder a trusted name for lithium battery conveying in Latin America. We have received inquiries from Argentina, Peru, and Ecuador. Our ability to adapt to high-altitude and local regulations makes us an ideal supplier. We provide remote diagnostics, spare parts, and on-site training.

Headpowder, short for Shandong Headpowder Engineering Co., Ltd., is based in Shandong, China. With experience in over twenty countries, we specialize in closed-feed, dense-phase, and dilute-phase conveying for powders ranging from lithium battery materials to food ingredients. Our team supports projects with site surveys, process design, and equipment selection.
