Because extremely fine powders tend to
agglomerate and therefore clog up the sieve, the air jet sieve is the
device of choice for sieving fine powders. This is where the air jet
sieve e200 LS develops maximum effectiveness. Not just one, but two
components work together here: a slotted nozzle which rotates inside the
sieving chamber and an industrial vacuum cleaner connected up to the
sieving chamber.
Once the vacuum cleaner is switched on, it
creates a vacuum inside the sieving chamber. The extremely narrow slot
of the slotted nozzle ensures that the incoming air is accelerated and
flows through the sieve cloth at high speed from below. The particles on
the sieve cloth are dispersed briefly by the air jet at the cover –
even before they are pulled downwards through the sieve cloth by the
suction of the vacuum cleaner. The effect: the fine material is
separated quickly and effectively. The coarse material remains on the
sieve and is reweighed at the end of the sieving process.
A
further advantage: the automatic underpressure regulation as well as
specification of the sieving-relevant parameters guarantee reproducible
results.
