New Cosmomizer (COS)

Product Outline

COS is a dry type, high speed impact type pulverizer with built-in classification mechanism. Basically, it consists of rotor equipped with pulverized blades, stator, classification structure that separates fine powder and coarse powder, and a self-circulation circuit that repulverizes coarse powder. Vortex flow generated by rotation of the rotor itself performs the classification function; therefore, power for classifier is not required. The construction is simple with excellent maintenance property.


  • Pharmaceutical, Foods, Cosmetics, Chemicals, Resin, Materials for Biomass, Feed/Fertilizer, Electronic Material, Fine Chemicals


  • Fine particles from several microns to several 10microns can be achieved.
  • Excellent milling efficiency since coarse powder is repulverized through self-circulation.
  • Excellent classification since the classification occurs at the place where particle is most dispersed just after the milling.
  • Disassembly and cleaning is easy since another equipment for the classifier is not used.
  • For milling of material with strong abrasion property, measurement against abrasion can be constructed.

Practical Use

  • Inert gas purge is available.
  • For milling of materials with strong abrasion property, ceramic rotor can be selected.
