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."

For production
Usable bead diameter
Centrifugal bead separation
Circulation operation / pass operation
Applicable with low to medium viscosities

Key Benefits


particle size distribution

Adopting a long body reduces short passes.

Processing with 30% UP efficiency than conventional mill


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


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

highly dense layer of beads

  • 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.

High-efficiency dispersed layer

  • 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

Conventional bead mill


Since the beads are pressed against the narrow space of the vessel or disc, it causes irregular heat generation, chipping, and overdispersion.

△Inefficient work

Conventional bead mill


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

NAM's Disk

Long life and high efficiency processing
Conventional bead mill

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.

  NAM-1 Conventional bead mill
Vessel capacity 0.8L 0.7L
Beads Zro2φ0.1mm ZrO2φ0.1mm

 Even particle size distributions are same,
the number of coarse particles that particle size analyzer can't detect by Neo-AlphaMill is 1/20 smaller than prior AlphaMill.

Good scale-up

Neo-Alpha Mill processed 20% Calcium Carbonate on 4 Scales (NAM-1,3,10,20)

Mill capacity ratio Production [kg / h] Comparison of production ratio
NAM-1 1 1.6
NAM-3 4 8 4times
NAM-10 12 18 11times
NAM-20 24 41 25times

  Even if the scale is increased, the processing performance does not change, and the production volume can be increased to the same level as the mill capacity.




Ink pigments / dyes, fine ceramics, catalysts, magnetic recording raw materials, etc.

※This specification is subject to change without notice due to improvements, etc.
※Explosion-proof specifications are required when using in places where there is a danger of ignition or when using organic solvents.
※The dimensions of the operation panel and relay terminal junction box will be fixed after the specifications are decided.
