Grinding/DispersingDual Apex Mill / DAM

DAM デュアルアペックスミル

The DAM is an advanced bead mill of the UAM in which the stirring rotor and bead separator can be independently rotated. This machine can be widely used for nano-dispersion with low damage to submicron grinding processing.

Overview

The DAM is bead mill that allows one to use the smallest class of microbeads from 0.015 mm. This machine is equipped with a centrifugal bead separator (Centri-separator) and realizes stable processing without clogging at the slurry discharge port. Because the stirring rotor and bead separator can be independently rotated, this machine can be used for the widest range of applications among our product lineup. In our product lineup, four types of bead mills equipped with a centrifugal bead separator are available.

Characteristics

1. The DAM can be used for a wide range of processing, from strong grinding to nano dispersion with low damage!
Regarding bead diameter, the condition is the same as that of the UAM (Ultra Apex Mill). However, because the bead stirring rotor and the centrifugal bead separator can be independently rotated, the peripheral speed of the bead stirring rotor can be freely changed from a low to high speed while maintaining the bead separating capacity. This machine can be used not only for strong grinding, but also for nano dispersion with low damage.
2. The DAM performs dispersion processing with reduced damage, even with nano particles.
Setting the bead stirring rotor to a low peripheral speed, damage to particles can be minimized, such that reagglomeration and an increase in slurry viscosity resulting from particulate fracture can be suppressed. It was previously difficult to realize such processing using former machine models.
3. The DAM can suppress bead wear and, therefore, reduce contamination from beads.
Because the DAM enables one to run the bead stirring rotor at low peripheral speed while maintaining the bead separating capacity, it can suppress bead wear and, therefore, reduce contamination from beads.

*The other characteristics are the same as those of the UAM (Ultra Apex Mill).

GlossaryHalf-value width is half the height of the peak value of the X-ray diffraction pattern. If the half-value width is narrow, the particles undergo low damage.
