Nebulasizer (NS)

For optimized size distributions

Nebulasizer is an innovative non-screen sizing machine that is utilizing the clearance between the rotary sizing ring and fixed sizing stator. Since no screen is required, the clogging or damage of it is avoided. Not only dry sizing but also wet sizing is possible, therefore generation of fine powders can be suppressed. Production with high process yield can be achieved with very sharp particle size distribution. There are many variations in the shape of sizing ring and stator, and countermeasures against abrasion and adhesion. Nebulasizer can be applied for different types of materials and application fields.


Pharmaceutical products, health foods, foods, chemical goods, fine ceramics, detergent, cosmetics, powder metallurgy, feedstuff, fertilizer


  • No clogging occurs with screen less design. Generation of off-grade products caused by the screen damage. 
  • Not only dry materials but also wet materials can be sized, therefore no fine powders are generated during the process.
  • Particle distribution of the product can be easily controlled by using the spacer for adjusting the clearance.
  • Powder adhesion can be suppressed by introducing hot air into the machine with the wet materials, to partially dry the surface layer of the material.
  • Different materials can be handled for different purposes via various types of sizing rings and stators.
  • Nebulasizer can be incorporated in line with various types of granulator such as extruder, agitating granulator, etc.


For type other than those above, we will design and manufacture in accordance with your request.
