micronized powders are an especial good quality, representing a revolution in
the cosmetic and pharmaceutical industries.

Mills from the family StarJet optimized with algorithms similar with the
presented algorithms were delivered and perfectly work from the year 2002, in
many enterprises for decorative cosmetic products of the societies Avon (USA),
Natura (Brazilia), Belcorp (Columbia), EverBilena (Taiwan), Swan Cosmetics
(Mexic), Cosmetica (Canada), GammaCroma (Italia), Hellenica (Grecia),
GiPiccos (Italia), etc.
The up presented algorithms, partially used in production, ask for verifications
and ulterior confirmations, forming the object of some future studies.
4. Conclusions
1. The research from what doctoral dissertation introduced an original threedimensional
model of the fluidic running in the spiral jetmills that describes
very veridical the complex jet in this kind of mills.
2. The results are obtained as suit of a very large gamut of theoretical and
experimental researches for the determination of the jets' speed.
3. The optimization algorithms were verified on models and in realty on 37
mills having different typo dimensions, in many fields (cosmetic,
pharmaceutics, and metallurgies) in above 20 countries.
