FRITSCH PULVERISETTE 14 - Manual (Page 29)

6.5 Removing the grinding elements
1. Lift off the lid of the collecting vessel (15) and, moving outwards
with a brush, clean the grinding stock from the outer surface of
the sieve ring (11) and from the inner edge of the collecting vessel
(8). If source material falls downward, it does not directly enter
the device; however, this should immediately be vacuumed away
with a vacuum cleaner (Ä Chapter 7 ‘Cleaning’ on page 41) after
removing the sample.
2. Remove collecting vessel (8) with the sample.
3. Use the vacuum cleaner to vacuum away the residual source
material
4. Remove sieve ring (11) and rotor (10).
It is important to remove the sieve ring (11) and rotor
(10) only after removing the sample, because incom‐
pletely milled sample material could be on either
part. There is a chance that this could find its way
into the milled sample and falsify the milling results.
5. Use a vacuum cleaner once again to vacuum away any residual
source material on the labyrinth disk.
6. Remove labyrinth disk (5). Because the labyrinth disk (5) is
clamped and centred with an O-ring, it can be somewhat difficult
to remove.
7. Clean parts before the next milling (Ä Chapter 7 ‘Cleaning’
on page 41).
