During powder processing and transportation, nano-silica often causes problems such as material blockages, dust pollution, and low conveying efficiency due to its small particle size, large specific surface area, and easy aggregation. How to achieve stable, sealed, and efficient nano-silica transport has become a core issue that many production processes urgently need to address.

Common pain points

When handling nano silica, enterprises often face the following challenges: materials easily adsorb the pipe wall, causing transportation interruptions; High-precision powder generates severe dust in open environments, affecting the working environment and employee health; Traditional mechanical conveying equipment wears out quickly, has high maintenance costs, and cannot meet the needs of long-distance, multi-point conveying. These issues directly restrict capacity improvement and process stability.

Material characteristics

Nano silica is an ultrafine inorganic powder with typical particle sizes between 10~100 nanometers, characterized by high specific surface area, low bulk density, strong hygroscopicity, and a pronounced agglomeration tendency. It has poor fluidity and is prone to bridging, wall adhesion, and material spraying under conventional conveying conditions. Therefore, the conveying scheme must fully consider the material's charge, agglomeration capacity, and the flow characteristics of the gas-solid phase, selecting appropriate conveying speed and gas source parameters.

Product Introduction

The nano silica pneumatic conveying system provided by Head Powder is a sealed pipeline conveying device specially developed for the characteristics of ultrafine powders. This system uses compressed air as power and stably delivers nano silica from the feeding point to the terminal via positive or negative pressure methods, with no dust leakage throughout the process, suitable for powder storage, mixing, packaging, and other process stages. The core components of the system include a rotary feeder, Venturi injector, cyclone separator, and intelligent control unit, which can be flexibly customized according to the user's on-site layout.

Product advantages

To address customer pain points, Head Powder focused on solving the following issues in its solution:
1. Anti-clogging and anti-sticking design — Uses special inner wall treatment and fluidized arch-breaking device to effectively suppress nano silica adhesion and blockage inside pipelines.
2. Sealed and dust-free operation—The entire system's sealed structure combined with high-efficiency dust removal components achieves zero-leakage conveying, significantly improving the working environment.
3. Low energy consumption and long service life—optimizing gas-solid ratio and airflow velocity reduces energy consumption while minimizing pipeline wear, extending equipment maintenance intervals.
4. Flexible customization capability—supports multiple working condition combinations from single point to multiple points, horizontal to vertical, short-distance to long-distance, and more, meeting different production line process requirements.
