Technical specifications
Machine designation:
AS300 control
Intended use
The AS300 control has been specially designed for analytical
sieves with a diameter of 305 mm (12“) to 315mm. This makes
the available sieving area 2.5 times greater than sieves with a
200 mm diameter. The AS300 control thereby allows the average
sieving times to be shortened.
A further benefit is the very high working quantity of material
to be screened (6 kg) which can be separated in one work proc-
ess. In case of frequently repeated sieve analyses made under the
same conditions, work is considerably simplified by the option of
storing up to 9 parameter combinations direct in the sieving
machine.
To ensure perfectly reproducible results, the AS300 control natu-
rally allows the power frequency independent control drive to
be specified instead of the vibration height. All sieving parameters
are set, displayed and monitored digitally. The amplitude is regu-
lated by a microprocessor-controlled measurement control unit
and is automatically re-adjusted if the loading or voltage changes.
The AS300 control can naturally be calibrated and can be there-
fore deployed as test equipment for quality control action under
DIN EN ISO 9000 ff. As with all "control" devices, the AS300 con-
trol also has an integrated interface.
The sieve can be actuated and adjusted by means of the
EasySieve
® evaluation software. EasySieve ® displays all sieving
parameters on the screen before and during the sieving process.
This machine is not intended as a production machine nor de-
signed for continuous operation, but rather as laboratory equip-
ment intended for one-shift, 8-hour per day operation.
The AS300 control is suitable for dry sieving of pourable, disperse
products with an input grain of max. 40 mm.
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.
