Screen sizes:
To obtain optimal efficiency, it is important to use
screens of correct slot/hole dimensions.
A range of screen sizes suitable for ordinary crops
is available.
Screen for inner drum
On the inner drum, the crop is to pass through the
screen and the large impurities be arrested.

Screens with a small hole diameter will therefore
ensure optimum separation of large impurities; at
the same time, however, the capacity will be re-
duced.
A large hole diameter, on the other hand, will result
in a high capacity and reduced separation of large
impurities.
As standard we recommend the same hole diam-
eter on the first two sections. However, in the event
of low capacities a better separating will often be
obtained by using a smaller hole diameter on the
1st and 2nd section. Still, the greater part of the
crop is to pass through the first 2 sections of the
inner screen.
