Dual Apex Mill (DAM)｜Wet Nano Particle Grinding & Dispersion System

Dual Apex Mill (DAM) is a wet grinding and high-efficiency dispersion system specifically designed for nano-scale materials. It enables homogenization, particle size reduction, and stable dispersion for a wide range of high-performance materials. The system integrates ultra-fine zirconia beads, centrifugal separation technology, a high-purity ZTA grinding chamber, and independently adjustable dual-shaft speed control, providing high flexibility and stability for nano-material development, scale-up, and advanced manufacturing processes.

Compared with conventional grinding mechanisms, DAM effectively suppresses heat-induced damage, particle agglomeration, and viscosity-related issues during processing. It is well suited for applications in energy materials, functional coatings, electronic ceramics, sensing materials, biomedical carriers, optical films, nano pigments, cosmetic nano-materials, and related fields.

Applications

• Energy materials: solar energy, fuel cell catalysts, lithium batteries, hydrogen energy conversion materials
• Environmental nano-materials: porous adsorption materials, photocatalysts, thermal insulation coatings, anti-reflection coatings
• Electronic ceramics and precision electronic materials
• Nanomaterials for biosensors
• Rare-earth nano-components and composite materials
• Drug delivery systems and biomedical nano-materials
• Optical films and optical component nano-materials
• Cosmetic nano powders
• Organic / inorganic nano pigments, dyes, and glazes

Key Features

• Supports ultra-fine zirconia beads ranging from Ø0.015 mm to 0.5 mm, delivering extremely high grinding efficiency.
• Grinding chamber made of high-purity ZTA material to ensure material purity and excellent wear resistance.
• Zirconia bead filling rate up to 60%–80%, significantly increasing energy density during grinding.
• Centrifugal separation mechanism eliminates the need for filter screens, prevents clogging, and allows easy control of pressure and temperature.
• Independent speed control for the agitation and separation sections (8–15 m/s and 2–12 m/s).
• Effectively suppresses viscosity increase and re-agglomeration of nanoparticles during grinding.
• Prevents lattice damage to nano-materials, preserving intrinsic material properties.
• Addresses nanoparticle agglomeration issues in colloidal and aerosol technologies.
• Supports continuous production, enabling smooth transition from pilot-scale to mass production.
