Procesy redukcji wielkości produktów takich jak materiały ceramiczne lub szkło są bardzo energochłonne.

Im drobniejsza granulometria, tym więcej energii jest potrzebne na proces mielenia. Dlatego też PULVIS został skonstruowany w celu zmniejszenia zużycia energii.

  • wartości rozdrobnienia do d97 < 1μm
  • stromy rozkład wielkości cząstek
  • do 80% oszczędności energii

Principle of operation

The milling part is located at the bottom of the machine. Feed material is ground by agitated media that combine impact grinding and attrition.

The gasflow injected from the bottom side transports and cools the particles on their way through the grinding media.

Ground particles are conveyed by air, passing through the grinding chamber to the classifier.

The classifier separates the required fine product from coarse particles. The coarse particles return to the grinding zone for further grinding.


  • Compact design
  • From Laboratory to production scale: with possibility to scale-up over complete range
  • Energy efficient: With high grinding efficiency specific energy consumption is reduced by up to 80 %. Finer particle sizes are possible compared to jet milling.
  • Ultra fine particles: The compact unit reliably produces very fine products with particle sizes in the sub-micron range.
  • Easy assembly: disassembly and cleaning are achieved with this design. Ideal machine for frequent material changes.
  • Wear protection: Mill and classifier are protected by ceramic lining and parts.


The PULVIS is the right choice for the ultra-fine grinding of hard, temperature un-sensitive materials. In the grinding process also additives can be used. Typical application for the PULVIS are for example:

  • Aluminium oxide
  • Anorganic pigments
  • Battery materials
  • Ceramic materials
  • Ceramic pigments
  • Glass, glass frits
  • Hydrogen adsorbent alloy
  • Industrial materials
  • Metal oxide
