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 3 sections of the
inner screen.
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.
