It seems plausible that both wet sieving and dry crushing yield different results for the OC distribution of the different aggregate size fractions. During wet sieving (especially with sonication), large primary particles are dispersed from fine particles (containing the most OC) (Nahidan & Nourbakhsh, 2018). This leads to an …

The former is called sieving before crushing, and the latter is called screening after crushing. Sieving before crushing means that the material after the first stage crushing is sieved before entering the second stage crushing inlet for crushing. So the output of the finished material is increased and the needle-like content is also increased.
