Dry milling hammer mill Fritsch

The FRITSCH Soil Deagglomerator almost completely automates the deagglomeration of soil samples and simultaneous removal of stones and a high sample throughput.

Field of application
Preparation of soil samples for chemical and physical analysis, e.g. to determine the active ingredients relative to crop yield or identification of pollutants. Agglomerates are reduced to 2 mm grain size, e.g. as per the sewage
sludge code or DIN 19683.

Method of operation
Agglomerated soil samples are crushed by the combined forces of impact and friction. Rotating spiral nylon brushes in a cylindrical grinding chamber gently deagglomerates the sample, simultaneously conveying the sample along a 2 mm perforated plate within the chamber. The processed sample is collected in a container at the base of the mill, whilst larger components (stones, glass, wood, etc.) are retained and finally separated out at the end of the grinding chamber.

Advantages

- Dust free operation through specially designed sealing
system
- Connection for dust extraction
- Accurate short-time timer for reproducible grinding conditions
- Continuous operation also possible
- Safety tested (CE mark)
- Speedy size reduction
- Easy to clean
- Overload protection
- 2 year guarantee
