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:
