The screen must have sufficient floating capacity after reinstallation; in other words, it must not be under
axial tension from the housing and the mouthpiece. If installed correctly, the screen can be moved some-
what 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. 13-11).

Normal screen wear (right)
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 transition can be
seen in this area (Fig. 13-9 left), the screen was
not installed again correctly after the previous in-
spection. In this case, the screen was damaged
due to insufficient floating capacity.
When you reinstall the screen, make sure that
the triangle stamped into the guide rod of the
" "
screen is up [12 o
13-10. If this original installation position is re-
tained, it is possible to identify the causes for any
uneven wear on the basis of wear marks.
