Achieved high-quality dispersion!
We will handle wide-ranging cases.
We will meet your advanced requests with the Mild Dispersion ® !
The dispersion process is intended to disperse aggregatesto primar y par ticles. However, applying excess energy
causes them to break into the primary particles.
This activates the new surfaces of the milled particles,
increasing interaction between particles on the activatedsurfaces, which results in reaggregation.
By controlling energy during par ticle dispersion helps
prevent over-dispersion. This particular method, known as

What is Mild
Dispersing®?

'Mild Dispersion,' is exclusive to the 'MAX Nano Getter.' Itachieves a balanced 'rolling force' of the beads in both
circumferential and axial directions, eﬀectively managing theshear forces of particles and beads. The 'MAX Nano Getter'
is a specialized bead mill designed to meet these conditions.
The 'MAX Nano Getter' can now disperse particles down tonano size s w hile cont ro lling ove r- disp e rsion w i t hou tdamaging them.

Mild Dispersion is Ashizawa Finetech Ltd.'s
original dispersing technology,
which maintains sizes, shapes, crystal structures,and surface conditions of primary particles.

Mild Dispersion

Conventional dispersion

Controls over-dispersion, and micronizes
particles with high quality and precision
without damaging them.

Over-dispersion is likely to increase particle
damage and promote aggregation.
Product characteristics are also likely to becompromised.

The 'spiral laminar ﬂow,' which considers balance between circumferential and axial directions,generates an ideal bead movement, resulting in damage-less, high-quality dispersion.

Achieve an ideal bead movement.
What is the ideal beadmovement?
Control ofcontamination

Beads stay uniformly in the griding chamber.
Beads are not over-dispersed.

(Eﬃciently contacts particles without applying strong shear forces.)

Regarding to wear and contamination, it is very important to select a millwhich doesn't use too much energy.
By the ideal beads movement, NANO GETTER and MAX NANO GETTER havegreat characteristics f high energy eﬃciency and they don' t give excessenergy which leads to contamination.

Bead movement in MAX Nano Getter®

The 'rolling force' of beads disperses particles.

Controls over-dispersion, and micronizes particles with high quality and precision, without damaging them.
