Micro and nano size reduction
Polymers, minerals, natural materials and carbon materials into the micrometre range – without liquid nitrogen, at our Magdeburg site.
Materials where standard processes reach their limits.
Why we report two distribution types
Number-weighted and volume-weighted distributions yield substantially different d50 values for the same sample. We report both separately: the volume-weighted one as the process figure, the number-weighted one as evidence of the finest fraction actually produced. Figures published without this distinction are not technically comparable.

Frequently asked questions
How fine can you reduce the particles?
That depends entirely on the material. Documented volume-weighted d50 values range from 3 to 151 µm, number-weighted considerably below. The binding answer for your material comes from the trial size reduction.
What quantities are possible?
From gram-scale samples to recurring batches in the tonne range. We clarify the realistic quantity before the trial size reduction, not after.
Do you use cryogenic size reduction?
No. Our process works without liquid nitrogen. That saves running costs for coolant.
What happens to my material if it does not work?
On request and against reimbursement of the shipping costs you get it back and learn why it failed.
