Machine type designation: SR 200
Application in the case of proper use
For uses where very frequently different materials have to be ground
and it is necessary to open the door to clean the grinding chamber after
every grinding operation.
The SR 200 is not designed as a production machine, but as a
laboratory unit, meant for 8-hour single-shift operation.
The SR 200 crushes dry, soft to medium-hard materials with a hardness
of up to about 4 according to Mohs.
It is especially suitable for the materials listed below:
and many other, similar materials.
The achievable end fineness depends on the hold width of the sieve
and the crushing properties of the material to be ground. In favourable
cases it is possible to achieve finenesses of < 60 µm.
For further information, please contact our application laboratory.
