Conclusions:

The amount of fine dust (particle size fraction < 32 µm) removed by preliminary sieving with the 32 µm sieve was determined to be 2.49 % of the applied mass. Mass fraction > 125 microns was 86.27%.

Description of key information

The amount of fine dust (particle size fraction < 32 µm) was 2.49 %  and mass fraction > 125 microns was 86.27%.
