Applicant's summary and conclusion

Conclusions:
99.07 % passed the 250 µm sieve
60.04 % passed the 149 µm sieve
28.90 % passed the 74 µm sieve
17.32 % passed the 44 µm sieve
Executive summary:

The particle size distribution of the sample was analysed through sieving. 5 Different sieves were with the following mesh size (250, 149, 74 and 44 µm). The following distribution was observed:

99.07 % passed the 250 µm sieve

60.04 % passed the 149 µm sieve

28.90 % passed the 74 µm sieve

17.32 % passed the 44 µm sieve
