Shaanxi Yulin Ultrafine Silicon Powder Closed Conveying System

Project Overview

A leading manufacturer in Shaanxi Yulin needed a reliable closed conveying system for ultrafine silicon powder. The existing open handling method caused dust leakage, material loss, and safety hazards. headpowder was engaged to design and install a fully enclosed pneumatic conveying solution tailored to the specific characteristics of ultrafine silicon powder.

Client Challenges

The client faced three main pain points: first, severe dust emissions from open conveying, leading to environmental compliance issues and worker health risks; second, high material waste, as ultrafine silicon powder is expensive and easily lost during transfer; third, inconsistent flow rates that disrupted downstream processing. The powder's extreme fineness and tendency to agglomerate further complicated conventional conveying approaches.

Our Solution

headpowder deployed a closed-loop dense-phase pneumatic conveying system with dedicated filtration and pressure control. The system uses sealed pipelines, automated valves, and a centralized PLC controller to ensure dust-free operation and precise material dosage. A custom-designed air feeder prevents agglomeration, while the closed design recovers all fugitive powder. The result is a stable, low-maintenance conveying process that meets strict environmental standards and reduces material loss to near zero.
