Applicant's summary and conclusion

Conclusions:
For the series of sieves between 1 and 4 mm, the majority of the particles (87.1%) was situated between 1 and 1.4 mm. The quantity of test item used for this series was 34.2% of the initial mass of test item used for the preliminary sieving.
For the series of sieves between 100 μm and 1 mm, the majority of the particles (86.8%) was situated between 710 μm and 1 mm. The quantity of test item used for this series was 65.6% of the initial mass of test item used for the preliminary sieving.
