Continuous Operation Type Dry Bead Mill
DRYSTAR SDA1
The Only Desktop Type Continuous Dry Bead Mill in the Industry
The DRYSTAR SDA1 achieves submicron-size particles by dry grinding without classifiers.
This machine has a 100 times better grinding ability compared to ball mills.
A trial can be started from 0.5L as a minimize volume.
User friendly design.
Structual drawing/Feature
- Achieving submicron-size particles by dry grinding
- Capable of testing 0.5 L as a minimum sample volume
- Particle diameter of 10 μm at maximum without using classifiers
- 100 times better grinding ability compared to ball mills
