Designed for wet nano grinding
Combine suitable small grinding balls, liquid and high energy input. A validated dispersion method is essential to achieving and measuring the desired distribution.
HIGH ENERGY. FINER POSSIBILITIES.
MM 500 nano.
Into the nano range.
Use high-energy impact and friction for routine preparation, demanding wet grinding and research. Two large screw-lock jars and up to 35 Hz provide a route toward nanoscale particles when the material and method support it.
Configuration examples. Accessories may be optional.
FEED SIZE*≤ 10 mm
FINAL FINENESS*~ 0.1 µm
FREQUENCY3–35 Hz
SAMPLE QUANTITY*2 × 45 ml
THE MODEL IN FOCUS
Ultrafine wet grinding & high-energy research
Large screw-lock jars
Two stations accommodate jars up to 125 ml nominal volume, with useful sample quantities up to 45 ml per station.
Research flexibility
Explore high-impact preparation, high-friction grinding, mechanical alloying and mechanochemistry with programmable cycles.
HOW IT WORKS
Oscillation.
Impact. Mixing.
Grinding jars oscillate in a horizontal position. The balls’ inertia drives them into the sample at the rounded jar ends. Impact and friction reduce the material while the motion mixes it.
Match ball size, number, jar material, filling level, frequency and time to the sample. Use smaller beads for compatible bead-beating methods; use a validated liquid and dispersion method for wet grinding.
Feed size, final fineness and useful sample quantity depend on the material, tools and operating conditions. Jar volume is not the sample filling volume. The finest result and largest feed or batch are not simultaneous guarantees.
METHOD & CONFIGURATION
A method for the result you need.
Larger balls emphasize impact; multiple smaller balls increase friction and mixing. Fine wet grinding adds liquid and a suitable dispersing strategy. Achieving about 0.1 µm requires an appropriate sample, grinding medium and sufficient process time; it is not the result of every short preparation cycle.
- Up to 35 Hz and two grinding stations
- 12 stored SOPs and four cycle programs
- Jars can remain clamped for subsampling after the mill stops
BUILD THE RIGHT SETUP
The tools make the method.
Select jars, balls and supporting accessories around your material and analysis. Confirm the complete configuration and what is included in the quotation.
Jars & grinding balls
Choose jar volume and tool material for hardness, wear and chemical compatibility. Options include hardened steel, stainless steel, tungsten carbide and zirconium oxide.
Multi-cavity jars
Optional small-cavity formats support parallel experiments with limited amounts of material. Confirm the compatible jar, sample quantity and loading method.
Atmosphere & monitoring options
Ask about aeration lids for a controlled jar atmosphere and GrindControl for temperature and pressure measurement inside the jar. These are optional accessories.
