With spiral jet mill technology, the size reduction is achieved by collisions between particles of the substance, previously accelerated by high-speed jet streams. Target PSD is generally below 30μm when adopting this technology.
The main advantages are represented by:
- Easy Cleaning for Validation (to avoid cross contamination)
- No mechanical parts in movement (no lubrication, strong reduction of metallic contamination)
- No Heat Generation
- Constant Temperature
Working principle
- High pressure gas (typically Air or Nitrogen), from 2 up to 12 barg
- Product particles acceleration in the milling chamber
- Particle to particle collision for product fragmentation
- Static classification
