13.3 INSPECTING AND REINSTALLING THE SCREEN
The wearing of the screen occurs primarily in
the area where the auger blades end in the
screen, i.e. at the transition to the pressing
area of the separator. If a sharp-edged transi-
tion can be seen in this area (Fig. 13-8 left),
the screen was not installed again correctly
after the previous inspection. In this case, the
screen was damaged due to insufficient float-
ing capacity.
When you reinstall the screen, make sure that
the triangle stamped into the guide rod of the
screen is
“
up
”
[12 o
’
clock position], see also
Fig. 13-9. If this original installation position is
retained, it is possible to identify the causes
for any uneven wear on the basis of wear
marks.
The screen must have sufficient floating capacity after reinstallation; in other words, it must not be un-
der axial tension from the housing and the mouthpiece. If installed correctly, the screen can be moved
somewhat by hand. A small gap of several tenths of a millimeter must exist between the mouthpiece
and the screen. This must be checked with a thickness gage (Fig. 13-10).
