This is a specialized pneumatic conveying case completed in Uppsala, Sweden. The project was delivered by Shandong Headpowder Engineering Co., Ltd., widely known as headpowder, a company headquartered in Shandong, China. It is a European pneumatic conveying case that focuses on the safe, stable and continuous transport of nano-scale powders that are highly prone to bridging, agglomeration, and flow interruptions.

Nano powders are extensively used in advanced ceramics, battery materials, catalysts, coatings, and pharmaceutical excipients. Because of their extremely small particle size and large specific surface area, strong inter-particle forces are generated. These forces often cause arching, ratholing, and cohesive blockages in conventional conveying equipment. In the Uppsala project, the material required a robust anti-bridge system capable of maintaining steady dosing and transfer performance over a long service period.

Headpowder solved this challenge with an anti-bridge pneumatic conveying system. The inlet hopper was designed with a steep mass-flow geometry and a low-friction lining to prevent stagnant material zones. Multiple aeration pads were installed along the hopper wall. These pads introduce micro air streams into the powder bed, reducing friction and promoting smooth flow. A fluidizing discharge cone was also added at the hopper outlet. This component actively breaks any arch that begins to form before it can stop the conveying process.

The conveying process uses dense-phase pneumatic conveying technology. Under this approach, nano powder is pushed as a high-density plug or stream at low velocity, instead of being suspended at high speed in dilute phase. Low velocity is essential because nano powder is sensitive to impact, heat, and mechanical stress. The system reduces particle degradation, wear on pipeline bends, and energy consumption. It is powered by an energy-efficient roots blower or screw compressor, depending on the required pressure and conveying distance.

The complete conveying line includes a pressure vessel type feeding system, a rotary airlock, an optimized conveying pipeline, a receiving filter receiver, and an integrated control panel. The filter receiver is equipped with pulse-jet cartridge filters to separate powder from conveying gas. A differential pressure transmitter detects filter build-up and automatically activates cleaning pulses. This prevents back-pressure and ensures stable pressure conditions inside the receiver.

For anti-bridge performance, Headpowder installed multiple safety devices. A low-level alarm and a high-level alarm in the hopper trigger automatic fluidizing action. The control logic starts the aeration pads, then activates an air knife at the outlet if no material movement is detected. The system supports fully automatic operation. All alarms and operating states are displayed on an HMI or PLC control screen, with remote monitoring available through industrial Ethernet or Profibus.

The main components are manufactured from stainless steel 304 or 316L, with surface finishing selected according to the product requirements. All gaskets are compatible with the nano powder and solvent-free cleaning agents. Electrical components comply with European CE requirements and can be supplied with ATEX-certified equipment for potentially explosive atmospheres. Project documentation includes P&ID diagrams, general arrangement drawings, operation and maintenance manuals, and a risk assessment report prepared in English to suit the Swedish customer.

This Uppsala nano powder conveying case is a strong example of European pneumatic conveying engineering. Shandong Headpowder Engineering Co., Ltd. carried out engineering design, equipment manufacturing, factory acceptance testing, and on-site installation guidance. The customer in Uppsala appreciated the clear communication and the smooth commissioning process. Since start-up, the system has operated reliably and significantly reduced manual intervention, downtime, and material loss caused by bridge blockages.

As a result, this anti-bridge pneumatic conveying case provides a valuable reference for other industries in Europe. If the powder is sticky, moist, very fine, cohesive, or easily compacted, the same engineering principle can be applied. Headpowder is able to supply a complete solution including an unloading system, storage silo, vacuum conveying, pressure conveying, safety controls, and process automation.
