Neo-Alphamill
NEO-Alphamill NAM
Neo-AlphaMill is a bead mill dedicated to nano-dispersion for production.
This machine produces high quality nano particles by a highly dense layer of beads and highly efficient dispersion layers with Delta-V Disks. These layers processes "all residual coarse particles" that cause quality deterioration.
"Goodbye, coarse particles."
φ0.03～0.3mm
Key Benefits
No.1
High-quality
nano-dispersion
～Drastic reduction of coarse particles～
The two areas ensure a depletion of coarse particles.
1/20 the number of coarse particles compared to conventional mills※
No.2
Sharp
particle size distribution
Adopting a long body reduces short passes.
Processing with 30% UP efficiency than conventional mill ※
No.3
long life
・The stirring materials have no protrusions.
・ Since there is only one rotating shaft, there is only one mechanical seal
Processing results for 4 years without replacement of parts※
No.4
Good scale-up
Even if NAM scales up, this machine can process production volumes equal to several times the mill capacity ratio.
26 times more production from NAM-1 to NAM-20※
※All values will fluctuate depending on the processing conditions.

Two areas that enable high quality nano dispersion
①Highly dense layer of beads
Area where beads are densely gathered by two centrifugal forces
- In the highly dense layer of beads, the flow of beads is slow and excessive energy is not applied, so that it is difficult to over-dispersion.
- The slurry always passes through the highly dense layer. It catches coarse particles in this area, preventing short passes.
② High-efficiency dispersed layer
Delt-V disc patented technology
Simple disc with no protrusions.
Special structure that produces centrifugal force, contraction flow, and circulating flow.
- The beads are circulated at high speed to increase the strength and frequency.
- The contraction flow creates a velocity difference, and the shearing force accelerates dispersion.
Highly dense layer space where beads move slowly
The beads move slowly to prevent overdispersion. Because it is densely packed, it can be reliably caught without missing coarse particles.
◎Efficient work
Since the beads are pressed against the narrow space of the vessel or disc, it causes irregular heat generation, chipping, and overdispersion.
△Inefficient work
When the space between the vessel and the disc is widened, the bead density is low and the processing speed is slow. Coarse particles may remain.
△Inefficient work
Structure that reduces wear
・Beads highly dense layer reduces wear because the speed of beads is slow.
・Disc shape without protrusions
Long life and high efficiency processing
Areas where wear is often observed
・Around the disc where the beads are moving at high speed
・Protrusions on/in Discs and vessel
Wear causes reduced efficiency
Processing example
Residual coarse particles that are not detected
by the particle size analyzer are drastically reduced.
