6.2 Principle of Operation
With the Air Jet Sieving Machine AS 200 jet only one single test sieve is used per sieving
process. The test sieve itself does not move during the sieving process. The movement of the
sample material on the sieve mesh fabric is achieved by a rotating air jet.
An industrial vacuum cleaner connected to the AS 200 jet generates a negative pressure in the
nozzle chamber by sucking ambient air through a silencer. The air jet generated this way exits
the rotating slotted nozzle at high speed and disperses the resting sample material from below
through the sieve mesh fabric. Above the sieve mesh fabric, the air jet is distributed over the
entire surface of the test sieve and is drawn off through the sieve mesh fabric at low speed. The
fine fraction of the sample material is transported through the sieve meshes and extracted with
the industrial vacuum cleaner. Optionally, the fine fraction can be collected in a cyclone
separator.
