Find a practical starting point.
Start with the material and the result. Compare a preliminary recommendation with the closest alternatives, then validate it with your sample.
SUGGESTED STARTING POINT
ZM 300 Ultra Centrifugal Mill
A flexible laboratory starting point for fine preparation of suitable soft, medium-hard and fibrous samples.
- Feed below 10 mm
- Published fineness below 40 µm
- Confirm material, dispersion-free dry preparation and sample quantity
This is preliminary guidance, not a performance guarantee.
Final selection requires a representative material trial and review of the complete configuration.

HOW ROTOR MILLS WORK
Apply the force.
Control the discharge.
A rotor accelerates material against tools, inserts or a screen. Impact, shearing or friction reduces it until the selected outlet and sieve allow discharge.
Match the feed.
Define the largest piece, hardness, brittleness, fibers and elasticity.
Set the operating point.
Choose rotor design, speed and sieve for the sample and target result.
Recover and evaluate.
Review collection, dust handling, size distribution and sample integrity.
COLLECTION & PROCESS CONTROL
Keep the sample.
Manage the heat and dust.
Compatible cyclone collection assists airflow and discharge, can reduce heat buildup and helps recover fines. Review the suction source, filters, vessel and complete installation for the selected mill.
- Higher recovery with an appropriate collection setup
- Cleaning methods to manage carryover between samples
- Temperature-aware preparation and sample handling
- Feeding, collection and downstream equipment integration
Cyclone collection does not make every process dust-free or suitable for hazardous powders. TWISTER includes a cyclone; options and cold-grinding compatibility vary on the other models.
MATERIALS & APPLICATIONS
Build the method
around the sample.
Grinding can prepare representative material, improve downstream mixing and support quality control. The sample and analysis determine whether a rotor mill is appropriate.
