Project Case of Dense Phase Pneumatic Conveying of Silica Powder for a New Material Enterprise in Jinhua, Zhejiang

In the field of advanced powder handling, the demand for efficient and secure transportation of fine materials has never been higher. One remarkable demonstration of this technology is the Zhejiang Jinhua New Material Enterprise Silica Powder Dense Phase Pneumatic Conveying Project. This project serves as a benchmark for the application of silica powder dense phase conveying in the production of high-purity electronic materials. The system was designed and engineered by Shandong Headpowder Engineering Co., Ltd., a leading provider of specialized pneumatic conveying solutions. The enterprise, commonly referred to as headpowder, is headquartered in Shandong, China, and has built a strong reputation for delivering reliable, contamination-free conveying systems for ultra-fine and high-value powders.

Project Overview and Core Application

The core of this project lies in the silica powder dense phase conveying case which demonstrates the ability to transport micron-sized silica particles over long distances without degradation or segregation. Silica powder, also known as silicon dioxide micro powder, is widely used in semiconductor encapsulation, optical fiber manufacturing, and high-performance coatings. The material's high purity requirement makes it extremely sensitive to contamination from metal wear, dust, or moisture. Therefore, the high-purity powder conveying technology employed in this project is critical. The dense phase pneumatic conveying system operates at low velocity and high pressure, creating a plug-like flow that minimizes particle breakage and abrasion. This gentle handling ensures that the silica powder maintains its original particle size distribution and chemical purity, which are essential for downstream processes.

Technical Features of the Dense Phase Pneumatic Conveying System

The dense phase pneumatic conveying system installed at the Zhejiang Jinhua facility consists of several key components including a pressure vessel, air control units, pipeline networks, and a receiving hopper. The system is designed to handle a conveying capacity of up to 5 tons per hour with a conveying distance exceeding 200 meters. One of the distinguishing features is the use of a proprietary bottom discharge valve that ensures consistent material flow even when dealing with cohesive powders. The system also incorporates a nitrogen purge mechanism to prevent moisture ingress and oxidation, which is particularly important for high-purity powder conveying. Additionally, the pipeline is lined with wear-resistant ceramic to extend service life and reduce maintenance costs. The entire process is controlled by a PLC-based automation system that monitors pressure, flow rate, and material level in real time, ensuring stable operation with minimal human intervention.

Advantages of Dense Phase Technology for Silica Powder

Compared to traditional dilute phase conveying, the dense phase approach offers several distinct advantages for silica powder dense phase conveying. First, the low velocity reduces particle attrition, which directly translates to lower dust generation and higher product yield. Second, the reduced air consumption leads to energy savings of up to 30% compared to conventional systems. Third, the compact design of the pressure vessel and piping allows for installation in space-constrained environments. For the Zhejiang Jinhua project, the client required a system that could handle both silica powder and other high-purity mineral powders without cross-contamination. The dense phase pneumatic conveying system was configured with quick-change filter elements and dedicated cleaning cycles to meet this requirement. The successful commissioning of this system has resulted in a 15% increase in production efficiency and a significant reduction in material loss.
