Grinding/DispersingUltra Apex Mill / UAM

Ultra Apex Mill / UAM

Standard model applicable to treatment with micro-beads, minimum size 15μm in dia., for nanoparticle grinding and dispersion.

Overview

Adopting a centrifugal separator for bead separation, the first in the world, this micro-bead mill can use beads of Φ15μm to 1 mm. Processing using microbeads of Φ0.1mm or smaller provides dispersion of slurry containing fine particles of 100nm or finer, such as fine inorganic powders, for example crude material of ceramics, electromagnetic materials, optical materials, etc. and pigments.
Among our bead mills, this model is the most widely applicable nanoparticle disperser; we have conducted several improvements on this model for widening its applications in these 20 years. This is the most suitable bead mill for dispersion processing submicron to nano-sized particles in general use.
It contributes to the technical progresses in the nanoparticle processing of barium titanate, organic chelate pigment, liquid crystalline coating agent, etc.
This bead mill can also be used for grinding of submicron to nano-sized materials since relatively large beads of Φ0.5 to 1mm can be used, thus this is a multirole bead mill. We also have sold units of this model for grinding API pharmaceutical crude chemicals of 200 nm or less. By inventing a micro bead separator utilizing centrifugal force, the first in the world, we have been awarded “Award for Prominent Master of the Manufacturing” and “the Science and Technology Award for Invention” from the Japanese Government.

Features

1.Microbeads are available for dispersing and grinding submicron to nano particle with this model!
UAM is capable of dispersing slurry of nanoparticles with a minimum diameter of 20nm because it can use microbeads with a minimum diameter of 15 μm. UAM has a structure of the agitating rotor with high dispersion force so that it has a high processing capacity.
2.Small and large beads are available to process multiple kinds of slurries in one unit!
UAM handles a wide range of bead diameters from φ15 μm to φ1mm. As it has a centrifugal bead separator, even if beads of different diameters are used, any mechanical adjustment is not necessary. Multiple kinds of slurries, such as pre-processing (large beads) and finishing dispersion (fine beads), are processed in a series without changing any mechanical part.
3.Easy disassembling and assembling, and easy slurry recovery!
Since it is a vertical bead mill and simply designed, it is easy to disassemble and assemble. It is also easy to recover slurry left in the mill.
4.Cleanability is also considered!
Some versions of this model have improved cleanability for applications with high hygienic requirements, such as food, cosmetics, and pharmaceuticals by redesigning shape and packing of corners and joints of the bead mill.
