This case study highlights the successful implementation of a long-distance pipeline pneumatic conveying system for rubber-plastic powder in Malmo, Sweden. The project was carried out by Shandong Headpowder Engineering Co., Ltd., widely known as Headpowder, a leading Chinese engineering company specializing in pneumatic conveying systems and bulk solid handling solutions. This installation is an excellent example of European pneumatic conveying, demonstrating how advanced engineering can overcome challenging material transport requirements in a demanding industrial environment.

The customer in Malmo, a prominent rubber and plastics processing facility, faced a critical operational challenge. The production process generated a significant amount of rubber-plastic powder that needed to be transported from the manufacturing area to a remote storage silo located several hundred meters away. Traditional mechanical conveyors were not viable due to the long distance, the need to avoid contamination, and the requirement for a totally enclosed, dust-free transport system. The existing handling method relied on manual labor and intermediate storage, which caused inefficiencies, increased product loss, and raised safety concerns for workers who were exposed to fine dust particles. The plant management sought a reliable, environmentally friendly, and cost-effective solution that could move the powder continuously and automatically over the long distance, while maintaining product quality and minimizing energy consumption.

After evaluating various alternatives, the client selected Headpowder to design, manufacture, install, and commission a bespoke pneumatic conveying system. Headpowder’s engineering team conducted a thorough analysis of the material properties, including particle size distribution, bulk density, moisture content, and abrasiveness. The results showed that rubber-plastic powder is light, slightly cohesive, and prone to agglomeration if not handled properly. Based on this analysis, Headpowder adopted a dilute-phase positive-pressure pneumatic conveying system with a carefully designed conveying velocity to ensure stable flow and prevent blockages. The system uses a high-efficiency roots blower to generate a steady air stream, which carries the powder through a specially selected carbon steel pipeline. A rotary airlock feeds the material into the conveying line at a controlled rate, guaranteeing consistent throughput and preventing backflow of air.

The long-distance nature of the project required precise calculations of pressure drop, air velocity, and pipe resistance. Headpowder’s engineers used advanced simulation software to model the entire pipeline route, including bends, elevation changes, and horizontal sections. The system was designed with an optimal pipe diameter and a number of strategically placed bends to minimize wear and pressure loss. To improve energy efficiency and reduce the risk of particle degradation, the conveying air velocity was carefully optimized. Additionally, the pipeline was equipped with an automatic purging and cleaning function, allowing the system to clear the line after each batch, which is particularly important for long-distance conveyance where residual material could harden or cause contamination. The control system integrates programmable logic controllers, variable frequency drives, pressure sensors, and flow meters, enabling fully automatic operation from a centralized control room. Alarm and diagnostic functions provide immediate feedback on any abnormal conditions, such as high pressure, low airflow, or blockage.

One of the key achievements of this project was the successful implementation of a long-distance transport line that reduced the plant’s reliance on manual handling. The system can convey rubber-plastic powder at a capacity that fully meets the production requirements, with a smooth and continuous flow even over significant distances. Because the entire conveying process is performed in a sealed pipe, dust emissions are virtually eliminated, creating a cleaner and safer work environment. The enclosed system also prevents moisture pick-up and contamination, preserving the quality of the rubber-plastic powder. In addition, the low-maintenance design of the pipeline and the robust construction of the blower and feeding components contribute to extended service life and lower operating costs.

From an economic and environmental perspective, the Headpowder system offers substantial benefits. The reduction of material waste, the lower energy consumption compared to mechanical conveyors, and the minimal need for spare parts translate into a rapid return on investment for the Malmo facility. The project also supports the company’s sustainability goals by reducing dust emissions and noise pollution. As a successful European pneumatic conveying case, this installation demonstrates that Headpowder’s technology is competitive not only in China but also in the demanding European market, where strict regulations on safety, environmental protection, and equipment reliability must be met.

In conclusion, the long-distance pipeline pneumatic conveying system installed in Malmo represents an outstanding example of how pneumatic conveying technology can solve complex material handling problems. Headpowder provided a complete turnkey solution, from system design and component manufacturing to installation supervision and after-sales service. The project has significantly improved the operational efficiency, product quality, and workplace safety for the customer. The success of this case has strengthened Headpowder’s reputation in Europe and led to further inquiries from other industrial companies looking for durable and efficient conveying systems.
