Applicant's summary and conclusion
- Executive summary:
Karbach A, 2009
Particle size distribution was analysed by image analysis after sieving (880µm).
The coarse fraction of the sample (845 µm - 16100 µm) with a mean diameter of 4228.6 µm was 99.61 %(w/w) .
The fine fraction (1.4 µm to 780 µm) was 0.39%(w/w) of the sample. It was analysed by light microscopy. The mean diameter of this fraction was 113.5 µm.
