Spiral Jet Mill
How It Works
High-purity raw materials are drawn into the flat chamber via negative pressure. Particles undergo supersonic self-collisions driven by airflow, eliminating mechanical wear. As fineness increases, the centripetal force diminishes, allowing qualified micro-powders to move toward the center for precise cyclone collection.
Performance Features
High-Purity & Versatile Adaptability
Ideal for dry grinding of materials under Mohs 9. Specifically addressing the stringent purity needs of Quartz & Silica Powder, this process prevents metal contamination, providing reliable ultrafine solutions for electronic and aerospace grade powders.
Cold & Media-Free Micronization
Supports constant or low-temperature, media-free micronization via self-grinding. It preserves the original physicochemical properties and interfacial activity of Quartz & Silica Powder, making it the premier choice for heat-sensitive or oxidizable high-tech additives.
Flexible Sizing & Narrow PSD Control
Achieves precise sizing from D50 = 2–100μm with a narrow particle size distribution (PSD) and zero oversized particles. The non-rotating parts design allows for rapid cleaning and process switching, significantly boosting the efficiency of fine production.
Robust Structure & Electronic-Grade Options
The CNC-machined single-plate main unit ensures exceptional durability with a weld-free structure. Optional wear-resistant ceramic linings or CIP functions are available to meet the high standards of the electronics and semiconductor sectors for equipment longevity and clean production.
