The plastic profile rails serve to dampen the impact shocks of the separator on the screen guide rails
and reduce friction.
The screen “floats” [“breathes”] in the guide rails, depending on how hard the solid cake is. The slight
up and down movement of the output regulator lever arms are an indication of the “floating” of the
screen in the separator housing.
Inspect both the screen and the plastic profile rails inserted into the guide rails for any wear. If uneven
wear is discernible on the plastic profile rails, these must be replaced with new ones. When inserting a
new screen, the plastic profile rails must naturally also be replaced.
Solid matter in the area of the guide rails must be washed out.
Never loosen the fastening bolts of the screen guide rails on the housing
as these are precision components that must be handled with care.
The screen guide rails are aligned during assembly of the sepa-
rator using a special template then fixed in place with the fas-
tening bolts and should not be loosened again. However, if the
setting is changed due to an error, they must be realigned. You
can obtain the required alignment template along with instruc-
tions from your nearest FAN dealer.
Follow the instruction in sections 6 and 7 to restart the ma-
chine.
Also clean the area in which the wear ring sits. This is located
at the rear of the housing at the transition to the inflow area and
is affixed to the housing with 3 bolts. This ring protects the
housing from wear as the screen “breathes” during operation.
The wear ring should be replaced no later than after radial wear
of approx. 1 mm
(when the inner diameter of the wear ring is approx. 263 mm) in
order to prevent screen damage.
For this, remove the 3 bolts and nuts of the wear ring on the
outside of the body. Pull the wear ring out of the screen hous-
ing and replace it with a new one.
