Technical specifications
Machine type designation:
AS400 control
Use according to the intended purpose
This machine is not intended as a production machine nor designed
for continuous operation, but rather as laboratory equipment in-
tended for one-shift, 8-hour per day operation.
The RETSCH AS400 control is used for dry sieving with analytical
sieve shakers of up to 400 mm in diameter. The uniform, circular
horizontal movement of the sieve precisely separates the material
to be screened with a maximum grain size of 63 mm.
Fine and coarse grained materials, such as those used in milling,
brewing, chemicals, stonework, earthwork, wood and plastic indus-
tries, can be separated precisely with the AS400 control.
The circular horizontal movement of the sieve is particularly benefi-
cial for separating certain products, such as milled grain, wood chips
and similar materials.
DIN 53477, for example, even specifies a circular sieve movement
for testing plastics (granular press masses).
The AS400 control can be deployed as test equipment for quality
control action under DIN EN ISO 9000 ff. The power frequency
independent control drive enables the AS400 control to supply
results reproducible anywhere in the world.
The speed/sieve plate acceleration and sieving time required are
set, displayed and monitored digitally. It is supplied with test certifi-
cate and can be calibrated. An arrangement to allow the direction
of turn to change at intervals can be linked in on request. Up to 9
sieve programs can be stored directly in the machine and called
up from there.
The AS400 control has an integrated interface to actuate all sieve
parameters via the EasySieve® software. The interface cable re-
quired for this is supplied as standard.
Do not make any modifications to the machine and only use Retsch
approved spares and accessories.
The conformity to the European guidelines declared by Retsch
otherwise loses its validity.
It furthermore leads to the nullification of all warranty claims.
The AS400 control can cause major imbalances due to movements of
the material being screened. It must therefore be installed on a suit-
able bench in the laboratory. The net weight of the AS400 control is 73
kg.
