Screens for outer drum
On the outer screens, the crop passes across the
screen while the small impurities will fall through.
Thus it is the slot dimensions of the outer screen that
determine the size of the impurities arrested.
During sorting, the separation of the crop looks takes
place on the outer screen.

OUTER SCREENS
Wheat Barley Oat
In selecting your screen you should also consider the
grain size, as a screen with too large slot dimensions
will also separate small-sized grains.
If an outer screen with oblong holes is used, it is
recommended to mount brushes to keep the screens
clean. For the grading of malting barley the brushes
must always be mounted (see section "Accessories").
