13.2 INSPECTION OF THE SCREEN AND THE GUIDE RAILS
The screen and the guide rails must generally be inspected every 1 to 3 months depending on the sepa-
ration medium.
For this inspection, the screen must be removed, cleaned with a high-pressure cleaner and then
checked for damage and traces of wear. The plastic profiles of the guide rails visible in the housing must
also be checked for an even contact pattern and good seating. Defective profiles can cause damage to
the screen.
When the screen basket is replaced, the plastic profiles must also be replaced with new ones.
To remove the screen and auger, do as follows:
1. Switch off the feed pump or stop the supply flow.
2. Remove the weights from the output regulator; open the flaps of the output regulator.
3. Allow the separator to run until no more liquid or solid material emerges.
4. Switch off the separator and the main switch on the switch cabinet, then secure the main switch
against reactivation (e.g. with a padlock).
5. Remove the bolt (internal brace) in the head of the auger. The length of the bolt is always the
same as the length of the auger. Remove the mouthpiece by unscrewing the 6 nuts that hold it in
place.
6. Loosen the lock nuts of the scraping bolts and turn the scraping bolts roughly one turn counter-
clockwise, see Fig. 13-13.
7. Remove the rest of the solid cake. You can use a large screwdriver for this. If the cake is very
hard, use a high-pressure cleaner to soften up the cake in order to pull out the auger and screen.
8. Pull out the screen, or, if it is difficult to separate the screen and auger because solid matter is
jamming the screen and auger, wash out generously with water. This will loosen the screen.
WARNING!
Never pound on the screen or the auger to loosen them as these are precision
components that must be handled with care.
The screen guide rails are situated inside the housing of the separator.
A plastic profile rail (T-rail) is inserted in the screen guide rails.
