Grinding

When you are facing problems related to micronization,
Ashizawa offer you the best solution by deciding whether thematerial is grinded or dispersed.
Labstar Mini is a laboratory sized bead mill with changeablechambers and agitators according to type of micronizing(grinding or dispersing). It is also changeable to batch typewhich is best for sampling a small amount of slurry.

MGF015①The Laboratory size MGF MillMGF015 is excellent for grinding particles to sub-micronsize.

②For Strong Shear Grinding

2Features

Particles are grinded in pieces from strong shear
movement of the beads. Dispersing in high viscosity
slurry needs strong shear power, which can beachieved using MGF015.

ForDispersing

The smallest size of NANO GETTER which is excellent fornano dispersing.

②Mild Dispersing

3Features

Combination of Centrifugal separator and screen, highviscosity slurry can also be operated.
Microbeads can be used, and this enables finer grinding level④High Energy Density Chamber

Narrow grinding area and the projections on theagitator produces great energy within the chamber,and move the beads strongly.

NANO GETTER DMS65①The Laboratory size mill of NANO GETTER“Rolling” power of beads can separate particles intopieces (see the right diagram). This “rolling” method
reduces the particles’ damage to the minimum.
Prevents re-agglomeration and contamination

Batch Type

③Centrifugal Separator with Screen

For grinding and dispersing③Screenless
Our original centrifugal separating system now allows
to operate without screen.
Easy handling of microbeads
Eliminates the pre-grinding process④Small L/D

Homogeneous movement of beads leads to higher
efficiency of energy.

NANO GETTER HFM02①Ideal Beads Movement for Dispersing

Straightening vane in the bead mill controls beads
movement. This realizes “Mild Dispersing” maintaining
high efficiency and high quality.
The Laboratory size mill of MAX NANO GETTER②The Minimum Sampling from 100mL

Batch type chamber doesn’t require other equipments
such as pumps, pipes, etc. HFM02 is ideal for tests usinga small amount of slurry.

Difference between Re-circulation
System and Batch System● Re-circulation System

Slurry in tank is pumped to the chamber to bedispersed. The slurry is pushed back to the tank again.
The slurry circulates through this system repeatedly.

Mild Dispersing is Ashizawa FinetechLtd.’ s original dispersing
technology, which maintains size,shape, a crystal structure, and asurface condition of a primaryparticle.

Mild Dispersing can disperse particles…
to primary particles without damaging their crystalstructure
