Results
Laser diffraction
Median values were calculated from unrounded values.

The median particle size L50(D (v, 0.5): 50% of particle volume or particle mass with lower particle diameter) deduced from these distributions were:
1sttest series L50= 377.0 µm; 2ndtest series L50= 378.7 µm
The average of the median particle size: L50= 377.8 µm

The particle size L10(D (v, 0.1): 10% of particle volume or particle mass with lower particle diameter) deduced from these distributions were:
1sttest series: L10= 174.3 µm; 2ndtest series: L10= 175.5 µm
The average of the particle size: L10= 174.9 µm

The particle size L90(D (v, 0.9): 90% of particle volume or particle mass with lower particle diameter) deduced from these distributions were:
1sttest series: L90= 654.6 µm; 2ndtest series: L90= 656.4 µm
The average of the particle size: L90= 655.5 µm

The particle size distribution showed a polymodal distribution. The maximum was seen at ca. 400 µm and a shoulder at ca. 70 µm.
