This article presents a comprehensive case study on the dust-free enclosed pneumatic conveying system for white carbon black (silica) in Marseille, France. The project was successfully delivered by Shandong Headpowder Engineering Co., Ltd., a leading engineering enterprise based in Shandong, China. The entire system is designed to achieve zero dust emission, fully enclosed material transfer, and high-efficiency pneumatic conveying tailored for the specific properties of white carbon black. This case serves as a benchmark for international pneumatic conveying solutions, especially for fine powder materials that are prone to dust pollution and moisture absorption.
The client, a chemical manufacturer located in Marseille, France, required a reliable and environmentally friendly material handling solution for white carbon black (also known as precipitated silica). White carbon black is a highly fine, lightweight, and abrasive powder with strong hygroscopicity. Traditional open conveying methods caused severe dust leakage, product loss, and workplace health hazards. The client specifically demanded a completely dust-free enclosed pneumatic conveying system that could operate continuously with minimal maintenance, while meeting strict European environmental and safety standards. Shandong Headpowder Engineering Co., Ltd. was selected as the engineering partner due to its proven expertise in pneumatic conveying systems for silica and similar materials.
The Marseille white carbon black dust-free enclosed pneumatic conveying system is a turnkey project integrating multiple advanced technologies. The core solution employs dense phase pneumatic conveying, which uses low velocity and high pressure to transport the material through pipes with minimal wear and degradation. The entire conveying line is hermetically sealed, preventing any dust leakage into the environment. Key components include a specially designed blow tank, rotary valves with airlock function, and a filter receiver equipped with pulse-jet cleaning. The system also incorporates a nitrogen inerting system to eliminate the risk of dust explosion, which is critical for white carbon black handling. All equipment is manufactured from stainless steel to resist corrosion and meet food-grade or pharmaceutical-grade requirements if needed.
White carbon black has unique characteristics that demand specialized engineering. Its low bulk density (typically 0.15–0.25 g/cm³) and high air retention make it difficult to fluidize. The system designed by Headpowder uses a patented fluidization nozzle and aeration pads to ensure stable material flow. The material is conveyed in a dense phase plug flow, reducing particle attrition and maintaining product quality. The conveying pipeline is lined with ceramic or wear-resistant materials to extend service life, as white carbon black is highly abrasive. A moisture control system is also integrated, using heated air and dehumidifiers to prevent caking during transport. These adaptations ensure that the pneumatic conveying case for white carbon black in Marseille achieves over 99% material recovery and zero dust emission.
The dust-free enclosed pneumatic conveying system is the highlight of this project. Every transfer point, from the storage silo to the blending station, is fully enclosed. The system uses a negative pressure pickup at the source and positive pressure delivery to the destination. All joints are sealed with high-performance gaskets, and the exhaust air is filtered through a high-efficiency cartridge filter with a filtration efficiency of 99.99% at 0.5 micron. The entire conveying process is monitored by a PLC control system, which automatically adjusts the conveying pressure, air flow, and material flow rate. In case of any abnormal pressure drop or leak detection, the system immediately shuts down and alerts the operator. This enclosed design not only protects the environment but also improves worker safety, as white carbon black dust is classified as a respiratory hazard.
The project was executed in the Port of Marseille industrial zone, a major logistics hub in southern France. Shandong Headpowder Engineering Co., Ltd. provided full engineering, procurement, construction, and commissioning services. The team worked closely with French local contractors to comply with European Union's ATEX directives for explosive atmospheres and the French labor code for occupational safety. The system was installed within an existing facility with limited space, requiring a compact layout. The dense phase pneumatic conveying system allowed for long-distance transport (over 150 meters) with fewer bends, reducing installation complexity. The project was completed on schedule, and the client reported a 30% reduction in energy consumption compared to their previous mechanical conveying system, along with a 100% elimination of dust emissions.
The Marseille white carbon black pneumatic conveying case demonstrates significant operational advantages. The system operates 24/7 with automated cleaning cycles, requiring only one operator per shift. The enclosed design minimizes product contamination and loss, saving the client approximately 15% in material costs annually. Maintenance is simplified due to the modular design: the blow tank, valves, and filters can be replaced without interrupting the entire system. The control system provides diagnostic data and predictive maintenance alerts, reducing unplanned downtime. For a typical white carbon black production line, the system can handle up to 10 tons per hour with a conveying speed of 0.5–1.5 m/s, ensuring gentle handling and consistent product quality.
