Title: Dust-Free Pneumatic Conveying of Carbon Black: Arequipa Case

Keywords: Pneumatic conveying case, Latin America pneumatic conveying, dust-free pneumatic conveying

In Arequipa, Peru, a manufacturing plant faced serious problems handling carbon black powder. The manual transfer from bags to processing equipment generated large amounts of dust, causing environmental pollution, health concerns, and significant material waste. To solve these problems, the company turned to Shandong Headpowder Engineering Co., Ltd., a leading Chinese engineering firm specialized in powder handling systems, and requested a completely dust-free pneumatic conveying solution.

Carbon black is a particularly challenging material for bulk handling. It is very fine, lightweight, and highly prone to becoming airborne. When handled in open environments, it spreads easily through the air, contaminating the workshop and posing a risk of dust explosions. Moreover, carbon black tends to adhere to surfaces and is difficult to move using traditional mechanical conveyors. Therefore, a closed pneumatic conveying system was considered the most suitable approach for this project.

After analyzing the customer's site conditions, material characteristics, and production capacity requirements, Headpowder designed a complete dust-free pneumatic conveying system. The system uses an enclosed pipeline network to transport carbon black from a centralized unloading station to multiple receiving silos and process machines. Because the entire conveying process takes place under negative pressure, no dust can escape into the surrounding environment. The layout was optimized for the existing factory space, minimizing the length of pipelines. This ensures that the factory floor remains clean and that operators are no longer exposed to hazardous carbon black particles.

The main equipment included a bag dumping station with dust hood, rotary airlock feeder, roots blower, dense phase pipelines, bag filter, and PLC control. Because carbon black has low bulk density and poor flowability, dense phase conveying was adopted to reduce wear and prevent pipe blockage. The bag hood captures dust at the source; the roots blower creates vacuum; the bag filter separates material from air. Field tests were conducted to set the exact air velocity and pressure for reliable conveying. A PLC-based unit monitors pressure, flow, and system status, allowing remote adjustments for stable operation.

The implementation brought remarkable improvements. Dust concentration in the workshop was reduced by over 95 percent, eliminating visible airborne carbon black. The working environment became safer and more comfortable. Material loss was reduced to nearly zero, leading to significant cost savings. Production efficiency increased because the new system conveys carbon black continuously without manual intervention. The customer's operating cost for labor and cleaning was also greatly reduced. The customer was very satisfied with the clean and stable operation.
