Nara Micros

Super‑Fine Wet Mill

A breakthrough alternative to traditional ball and bead mills, the Nara Micros utilizes a high-speed milling ring that both rotates and revolves within a jacketed vessel. As the ring presses material against the vessel wall, it generates intense compressive and shear forces, enabling rapid particle reduction to the single-micron or sub-micron scale in just 20–30 minutes

Key Highlights for Your Application Needs

High-viscosity slurry capability: Efficiently processes slurries with viscosities that challenge conventional mills
Organic solvent compatibility: Handles solvent-based systems safely.
Temperature control: Jacketed vessel allows precise cooling or heating of slurry
Fast milling time: Delivers fine dispersion much quicker than ball or bead mills
Flexible operation modes: Supports batch, continuous, or external circulation processes

Advantages

Fast & efficient – rapidly achieves sub-micron dispersion in high-viscosity mediums

Heat management – avoids thermal degradation through active cooling

Scalability – from lab‑scale MIC‑0 to industrial‑scale MIC‑30

Operational flexibility – batch, continuous, or circulation modes support diverse production setups

Easy media separation – milling rings are fixed to the subshaft for simple removal

Ideal For

R&D labs refining particle sizes

Production facilities requiring fine dispersion of pastes, inks, and nano-formulations

Industries demanding rapid turn-around and high-throughput wet milling

How our wet milling technology works?

At the heart of the Nara Micros is a high-speed rotating and revolving milling ring. This ring moves inside a jacketed cylindrical vessel designed for active temperature control. As the ring presses material outward against the inner vessel wall, it creates a powerful compression and shearing environment that rapidly disintegrates agglomerates and reduces particle sizes to the sub-micron or nano range. Unlike traditional media mills, there are no grinding beads to manage or separate, reducing downtime and contamination risks.

The result is:

Finer dispersion in a fraction of the time
High throughput even with viscous or thixotropic slurries
Better energy efficiency and lower operational noise
