Handling PTFE micropowder presents unique challenges in pneumatic conveying due to its fine particle size, tendency to agglomerate, electrostatic buildup, and abrasive nature. Many processing facilities experience frequent blockages, inconsistent flow rates, equipment wear, and product contamination. These issues lead to production downtime, increased maintenance costs, and compromised product quality.

Material Characteristics

PTFE micropowder is characterized by low bulk density, high surface area, and strong electrostatic charge generation during movement. The particles are typically sub-micron to a few microns in size, with excellent lubricity but poor flowability when not properly aerated. Additionally, the material can be sensitive to temperature and moisture, requiring careful handling to maintain its performance properties.

System Solution Overview

headpowder offers custom-engineered pneumatic conveying solutions specifically designed for PTFE micropowder. Our systems integrate dedicated component selection, inert gas options, electrostatic dissipation mechanisms, and gentle conveying paths to preserve particle integrity. Each solution is tailored to the facility layout, throughput requirements, and downstream process integration. We provide complete turnkey systems including feeders, conveying lines, receivers, filters, and control systems.

Key Advantages Addressing Customer Pain Points

To overcome common conveying difficulties, our system incorporates several engineering measures:

• Electrostatic control: Grounded conductive piping and specialized antistatic liners prevent charge accumulation and reduce safety risks.
• Low-wear design: Smooth internal surfaces, gradual bends, and low-velocity conveying minimize equipment erosion and product degradation.
• Anti-agglomeration: Continuous air injection and vibration options prevent bridging and maintain consistent flow.
• Sealed environment: Closed-loop conveying with optional nitrogen purge protects the powder from moisture and contamination.
• Custom control: PLC-based automation allows precise adjustment of air velocity, pressure, and feed rate to match material behavior.
