3.8 Feed Grain Size
Traditional dry sieving is performed in the particle size range of 40 µm to 125 mm. By means of
sieving aids or with wet sieving the measurement range can be extended to 20 µm. The
maximum feed grain size depends on the sample material, the number and aperture size of the
test sieves and the type of the sieving machine.
Examples for the maximum feed grain size according to DIN 66165 are listed in the following
table:

The Air Jet Sieving Machine AS 200 jet is designed for the measurement range of 10 µm to
4 mm.
3.9 Negative Pressure
NOTICE The maximum negative pressure, generated by an industrial vacuum cleaner or an
external suction device must be < 100 mbar (10 000 Pa or 1.45 psi)!
3.10 Payload
Depending on the mesh size of the test sieve used ( Chapter "Receptacle Volume") and the
density of the sample material, the maximum payload is 0.3 – 100 g.
NOTICE If the test sieve is overloaded, it can be damaged as the sample material clogs the
meshes and the negative pressure can thus exert too much force on the sieve mesh fabric.
3.11 Suitable Sieve Diameters
 Suitable sieve diameters: 200 mm / 203 mm (8")
