Zhejiang Hangzhou Nano Silica Powder Conveying Case

Case Overview

A leading manufacturer in the advanced materials sector encountered significant challenges in transferring nano silica powder from storage to production lines. The company engaged Headpowder to design and implement a dedicated pneumatic conveying system tailored to the unique flow characteristics of nano-scale powders.

Client Challenges

The client faced three primary difficulties: severe dust leakage during conventional screw conveying, frequent pipeline blockages due to agglomeration of nanoparticles, and inconsistent feed rates that compromised final product quality. Additionally, the existing system required excessive manual cleaning intervals, leading to high maintenance costs and production downtime.

Headpowder Solution

Headpowder deployed a dense-phase pneumatic conveying system with an integrated de-agglomeration nozzle. Key features include a closed-loop negative pressure design to eliminate dust emissions, a specialized hopper agitation mechanism to prevent bridging, and a PLC-controlled flow meter for real-time rate adjustment. The system was tested under actual production conditions in Hangzhou, Zhejiang, delivering consistent throughput with minimal particle size degradation.

Operational results showed a 40% reduction in maintenance downtime, dust concentration below 0.5 mg/m³ at the conveying area, and a steady feed accuracy within ±1% of the set point. The solution enabled the client to scale production without compromising workplace safety or product consistency.
