3. Fasten the bent tube support there.
4. Insert the paper filter sack (2) in the nylon support sack (4) and
clamp it firmly at the plastic flange (1) with the clamping ring (3).
Make sure that the nylon support sack has been slid over the

Carry out the installation and removal of the grinding elements as well as
the milling process as described in Ä Chapter 6.3 ‘Installing the grinding
elements’ on page 27, Ä Chapter 6.5 ‘Removing the grinding elements’
on page 29 and Ä Chapter 6.4 ‘Conducting a grinding operation’
on page 28. The only difference is that the tube to the collecting vessel is
inserted in and fastened to the bent tube support.
6.7 Grinding with external cooling
For certain source materials, using coolants before milling can be benefi-
cial for comminution. For instance, soft organic materials or special plas-
tics can be made brittle by briefly immersing them in liquid nitrogen or
storing them in a freezer. The source material, however, should be pro-
tected against condensation - e.g. a plastic bag could keep the source
material dry during cooling until milling.
