In a specialized electronic materials production project in Yibin, Sichuan, the client needed to build an engineering system for conveying silicon micropowder. As a high value-added powder material, silicon micropowder requires extremely strict purity; any foreign impurities mixed in may lead to product downgrade or even scrapping. The customer's original conveying method had issues such as dust leakage and cross-contamination, and internal residues were difficult to clean, seriously affecting product qualification rates and production efficiency.

Customer pain point analysis

1.Contamination risks under high-purity requirements: Silicon micropowder particles are extremely fine, and traditional conveying equipment easily generates metal friction debris, rubber wear particles, and other foreign substances during operation, directly contaminating the material.
2.Insufficient sealing performance: Poor sealing at ordinary pipeline connections and dust leakage not only causes material waste but also pollutes the workshop environment, making it difficult to meet clean production requirements.
3.Cleaning and maintenance are difficult: The internal structure of the conveying system is complex, making it difficult to fully remove residual materials, and cross-contamination is likely to occur during batch switching, affecting product quality stability.
4.Energy consumption and efficiency are at odds: The original equipment used low-speed conveying to achieve pollution-free operations, which limited production capacity and could not match the high-speed feeding needs of the front-end production line.

Head Powder Solutions and Advantages

To address these pain points, Head Powder has customized a high-purity, pollution-free sealed conveying system for the project, optimizing everything from equipment selection and material selection to control schemes:

Fully enclosed piping design: Uses seamless stainless steel pipes and dedicated sealing joints, maintaining slight negative or positive pressure inside the system to prevent dust from escaping and preventing outside air and impurities from entering, ensuring a clean environment throughout the entire process.

High-purity materials and low-wear processes: All parts in contact with materials are made of food-grade or electronic-grade stainless steel (such as 304L/316L), with inner walls finely polished for low friction coefficient; Combined with specially designed elbows and valves, it reduces material impact and wear, controlling the generation of metal foreign objects from the source.

Intelligent cleaning and rapid production changeover: The system integrates automatic purge and pulse back-blowing functions, enabling comprehensive cleaning of pipelines between batches; The modular structure facilitates disassembly and maintenance, reducing production changeover time to one-third of traditional equipment and effectively preventing cross-contamination.

Efficient and energy-saving conveying: Adopts pneumatic conveying principles, precisely adjusting airflow speed and concentration ratio, achieving stable and efficient conveying while ensuring material integrity. Single-line capacity can exceed 5 tons/hour, reducing overall energy consumption by about 25%.

Currently, the project has been successfully put into operation. Customers have reported that product purity has increased to over 99.9%, workshop dust concentration has dropped below detection limits, and continuous operation reliability has exceeded expectations, making it a benchmark case for high-purity powder conveying in the industry.
