The finer the particles to be produced,

the higher the energy that is needed

for the production. That is why we at

Hosokawa develop technologies allowing

our customers to produce finer and finer

particles at reduced energy consumption.

The PULVIS, a combination of a vertical

agitated ball mill and a high performance

air classifier represents a further milestone

on our way.

The PULVIS was developed as an energy-efficient ultra-fine grinding machine. This high-efficiency mill produces sub-micron size particles.

FEATURES

- 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 more

than 80%. Finer particle sizes are possible

compared to jet milling.

- Adjustable particle size

Fineness is determined by changing the

classifier speed.

- Ultra fine particles

The compact unit reliably produces very

fine products with particles sizes in the

sub-micron range

- Easy access

Easy assembly, disassembly and cleaning

are achieved with this design. ideal

machine for frequent material changes.

OPERATING PRINCIPLE

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

reqired fine product from coarse particles.

The coarse particles return to the grinding

zone for further grinding.

APPLICATIONS

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:

- Anorganic pigments,

- Ceramic materials

- Metal oxides

- Battery materials

- Industrial minerals

- Glass, glass frits

- Hydrogen adsorbent alloy

- Magnetic materials (process with inertgas)

- Graphite

WEAR PROTECTION

Grinding parts and classifying

parts are available

- in various ceramic qualities

Grinding beads

- Zirconia qualities

If the product has to be free of any contamination, then a jet mill or an

autogenic grinding has still to be chosen for grinding.
