However, the finer particles were not removed from the sample, and using tetrabromoethane prior to dry sieving had little to no effect on the distribution of particles in the final sample. Several workers ultrasonicated their respective samples in aqueous suspensions after dry sieving to remove fine particles from the pyrite surface [14,17,23 ...

Six steps were followed: washing, crushing, milling, dry sieving, wet sieving, and sedimentation. The glass, collected as waste glass, was washed and dried before crushing to remove any residues. After crushing to particles that passed through a 1.18 mm sieve (ASTM no. 16), the glass particles were further processed in a laboratory ball mill.

Particle-size distribution - Wikipedia

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
