Fujian Xiamen Filler Powder Pneumatic Conveying Project

In the filler powder processing industry, the efficient and clean transfer of bulk materials is a critical operational challenge. A leading manufacturer in Fujian Xiamen approached us with a series of technical bottlenecks in their existing powder handling system. This project illustrates how a carefully engineered pneumatic conveying solution can resolve these issues while improving overall production reliability.

Client Pain Points

The client's existing material handling method relied on manual feeding and open conveyor belts, which led to significant dust leakage, material spillage, and frequent equipment blockages. The filler powder, with its fine particle size and low bulk density, tended to agglomerate under humidity changes, causing inconsistent flow. Maintenance costs were high due to frequent cleaning and component wear. Additionally, the lack of automation required constant operator supervision, limiting production capacity and exposing workers to airborne dust.

Solution Provided

Headpowder designed and installed a closed-loop dilute phase pneumatic conveying system specifically tailored for the filler powder's flow characteristics. The system uses a positive pressure fan to transport the material through stainless steel pipelines from the storage silo directly to multiple production stations. A specialized dehumidification unit at the intake prevents moisture absorption, while an automated control system adjusts the air-to-material ratio in real time. This approach eliminates dust emissions, reduces material loss to below 0.5%, and enables continuous 24/7 operation with minimal manual intervention.

Technical Highlights

The conveying line incorporates a series of wear-resistant bends and a proprietary airlock feeding mechanism to handle the abrasive nature of filler powder. A baghouse filter at the receiving end captures any residual fines, ensuring that the working environment remains clean. The system's variable frequency drive allows operators to adjust conveying speed according to downstream equipment demand, further optimizing energy consumption.
