Principle of Operation

Suction side
Intake nozzle
The suction blower consists of a
powerful blower and a rotary valve.
Conveying is started by using the
suction air of the blower to lift and
accelerate the grain towards the
blower.
Function of air regulator
The blower is provided with an
automatic air regulator positioned in
the pipe between the cyclone and
the blower intake.
The purpose of the air regulator
is to limit the max. air speed to
the ideal conveying speed of
approximately 25 m/sec. Thus grain
damage owing to excessive speed
as well as overloading of blower will
be avoided.
The air regulator is plumbed from
the factory, and the adjustment may
not be changed.
Blower Rotary valve
Just before the grain reaches the
blower housing it is separated from
this air stream in a cyclone and
dropped into the rotary valve. The
rotary valve conveys the grain from
the suction side in the cyclone to
the pressure side in the transport
pipe.
The air regulator for
SUC500/700/1000 should always
face as shown in fig. A or B,
otherwise the conveying capacity
would be reduced.
Suction
cyclone
Pressure side
Grain is carried to the outlet
cyclone in an air stream. The outlet
cyclone stops the grain, before
it comes out of the outlet in the
bottom of the cyclone. The air is
blown out through the top of the
cyclone.
Safety filter
Especially for SUC 1000 TR
The filter in the suction cyclone of the
SUC 1000 TR is with open bottom.
In order to avoid grain being sucked
into the blower by an accident, safety
filter is mounted in the pipeline between
the cyclone and the blower. The filter
must always be placed as shown on
the filter.
The filter will normally only start working
if the cyclone, by an accident, is
overfilled. This may occur, if the rotary
valve stops due to a broken V-belt, or if
the exhaust cyclone is blocked.
