Unique Technology – Vortex Milling

The theory beyond the invention claims that a particle will break along its weak points when it is exposed to certain aerodynamic conditions. The vortex mill creates those aerodynamic conditions Similar to the conditions in a Tornado storm. Aerodynamic forces are the main driver for particle reduction in our mill.

The SuperFine Vortex mill comprises a compact vortex chamber with no moving parts, which is unlike other milling technologies that are based on mechanical forces.

The principle is also different than in other air-jet mills: our technology is based on subjecting the particle to rapid changes in air pressure and flow directions. Hence, the particle is breaking along its natural dents, cavities or crystal defects. The result is a “clean cut” that is not accompanied with compression or amorphization of crystal surface typical to standard jet-mills. 

This is a “soft milling” process providing:

  • No Trauma to the material

  • Protection from degradation or amorphization

  • Handling soft, elastic substances.

The special airflow dynamics in the system imply that the lowest air pressure point is located within the micronizer. There is no Venturi injector or inlet hoppers that could clog.

The milling process of the SuperFine Vortex mill is a continuous process. The final milling results are achieved in one milling stage. There is no need for multi-pass milling.

SuperFine’s Vortex mills require an air supply at a pressure of up to 6 bars. Compared to other mills that use compressed air,

our technology consumes much less air in the same conditions when milling a specific material.
