A leading materials processing company in Melbourne, Australia, specializing in high-performance polymers, required ultrafine PTFE (Polytetrafluoroethylene) powder for advanced applications in coatings, lubricants, and composites. PTFE’s unique properties (such as low friction, chemical resistance, and thermal stability) make it challenging to micronize without generating heat or contamination, as traditional mechanical milling can cause material degradation or inconsistent particle sizes. The customer approached Epic Powder Machinery seeking a reliable, high-efficiency jet mill for PTFE particle size reduction.
After evaluating their requirements, we recommended our MQW20 Fluidized Bed Jet Mill, known for its precision classification, low-temperature grinding, and ability to handle heat-sensitive materials like PTFE through particle-on-particle collision.
The MQW20 delivered exceptional performance, achieving a consistent D97 of 18 μm with a narrow particle size distribution. The jet mill’s integrated classifier ensured precise control, minimizing oversize particles while maximizing yield. No significant heat buildup occurred, preserving the PTFE’s material integrity.
Customer Benefits:
- High throughput of 107 kg/h enabled efficient scaling for production needs.
- Superior powder flowability and dispersibility improved end-product performance in coatings and additives.
- Clean, contamination-free processing with no moving parts in the grinding chamber.
- Energy-efficient operation reduced overall costs compared to alternative milling methods.
The customer in Melbourne reported full satisfaction with the results, noting improved product quality and consistency. This successful application demonstrates the MQW20’s excellence in ultrafine grinding of challenging polymers like PTFE.
Epic Powder Machinery continues to support global customers with tailored jet milling solutions for superior micronization results.
