Operating principle
The generated vacuum presses the grains
against the rotating metering disc (6) which
transports them further.
The separator (7) scrapes off the excess grains.
There is one grain each in each hole of the
metering disc.
At the grain dispenser (9) the grains are sepa-
rated from the metering disc and released into
the downpipe.
The ejection wheel (12) removes stuck grains,
broken grains or foreign particles from the holes
of the metering disc.
