Pneumatic Conveying of Chemical Filler Powder in Helsinki

This case study presents a pneumatic conveying system for chemical filler powder in Helsinki, Finland, delivered by Shandong Headpowder Engineering Co., Ltd. (headpowder). This is a representative pneumatic conveying case in Europe, demonstrating modern pneumatic conveying in Helsinki. Headpowder, based in Shandong, China, specializes in dense-phase and dilute-phase conveying for powders and bulk solids. The client, a Finnish chemical manufacturer, needed a dust-free, efficient method to move calcium carbonate filler powder from storage silos to production lines while meeting strict Finnish environmental and safety regulations.

The filler powder had a bulk density of 0.8 t/m³, a mean particle size of 10 microns, and a moisture content below 0.2%, making it prone to fluidization, clogging, and degradation if handled improperly. The conveying route was 185 m horizontally and 22 m vertically, with nine bends. Headpowder used CFD simulations to optimize pipe diameter, bend radius, and air velocity, then selected a pressure-vessel dense-phase system that moves the powder gently in slugs, reducing equipment wear and product breakage.

Main equipment included a 1.5 m³ pressure vessel, a variable-frequency drive (VFD) roots blower, ceramic-lined pipe bends for abrasive resistance, and a control system with a programmable logic controller (PLC) and human-machine interface (HMI). The PLC continuously adjusts air flow and pressure in real time based on material sensors, ensuring stable operation even during Helsinki's cold and humid winters. All components had an IP rating suitable for outdoor Nordic use.

Because the dust can form an explosive atmosphere, the system was engineered to the ATEX directive. It included explosion-relief panels, grounding and bonding of metal parts, and a nitrogen purging option for safe maintenance. A HEPA filter on the dust collector kept emissions below 5 mg/Nm³, a level stricter than Finnish requirements. The complete system was pre-assembled and tested at headpowder's facility in Shandong, greatly reducing on-site installation time.

Installation was completed in four weeks by headpowder engineers and local Finnish contractors. Performance tests confirmed a conveying capacity of 12 tons per hour, an air-to-material ratio of 15:1, and a power consumption of only 0.23 kWh per ton. The client's laboratory verified that the particle size distribution and specific surface area of the filler were unchanged after conveying. Blower noise was measured at 78 dB(A) at one meter, compliant with occupational health limits.

Commissioned in early 2024, the system has operated for more than 6,000 hours without unscheduled downtime. Remote diagnostics allow headpowder's engineers in Shandong to monitor PLC data in real time, enabling predictive maintenance. This successful pneumatic conveying case in Europe has strengthened headpowder's reputation in Helsinki and across the continent, and it serves as a benchmark for future filler powder conveying projects in Europe.
