Impurities separated by screens and aspirator
discharged into the trash blow line
Mount the covering plate in the outlet (B) and (C) of
the trough auger.
Impurities separated by screens and aspirator
discharged separately
Remove the covering plate from the outlet (B) of
the trough auger. If desired a shutter may be fitted
instead of the covering plate.
Oversized impurities separated by inner screen can
also be discharged separately.

Capacity:
Maximum capacity of the combi cleaner for pre-
cleaning of grain is approx. 40 tons/hour.
Generally, the capacity will depend on the required
cleaning efficiency - the smaller the load on the
screens, the better the separation of impurities.
The conveying system should therefore be de-
signed to allow adjustment of the material supply
to the cleaner, to obtain the desired cleaning ef-
ficiency.
General advice concerning capacity and selec-
tion of screens:
The inner screen separates the large impurities
from the crop. The main flow of crop has to pass
through the inner screen. Selecting screen with
small hole size compared to the kernel size gives
the most efficient cleaning, but reduces capac-
ity. Selecting screen with large holes compared to
kernel size gives capacity but reduce cleaning ef-
ficiency. If too much crop is feed into the KDC 4000,
good kernels will be discharged together with the
impurities.
To reach max. capacity it is then necessary to
use screens with large enough holes to allow the
kernels to pass through fast enough. On the outer
screen small impurities and small kernels are sepa-
rated from the crop. For pre cleaning, there is no
limitation in capacity in relation to screen selection.
For size separation of kernels on the outer screen
approx. 10 – 20% of the capacity rated for pre
cleaning can be obtained.
Inclination:
In case the cleaner should be used for pre cleaning,
it is advised to adjust the inclination to approx. 5° to
the rear.
5°
At an inclination of approx. 4,5° the inner screen is
horizontal at the bottom. The inclination must there-
fore never be less than 4,5° as the inner screen
should either be horizontal or incline towards the
outlet end.
The angle of inclination should normally never
exceed 7°. The pipe connections for the cleaner
should therefore minimum allow adjustment of the
inclination. If the cleaner is also going to be used
for separation inclination may vary from 5° - 12°.
Connect, for instance a flexible steel hose to the
inlet and the fan discharge opening (Kongskilde
product no. 122 050 156).
For adjustment of the working angle use the gradu-
ated scale on the side of the cleaner.
Set the arrow to the desired number of degrees.
Now raise the inlet end of the cleaner using a lifting
jack, until the spirit level indicates horizontal.
Adjust the length of the cleaner legs to rest on the
floor and lower the jack. Ensure that the cleaner
rests on all four legs. The cleaner must not rest on
the jack during operation.
In case the cleaner is equipped with tilting equip-
ment (accessory), use the crank located at the
outlet end, to raise the cleaner, until the spirit level
indicates horizontal.
