The particlesize 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.

Different methods for measuring particle size distribution (PSD) and specific surface area of crushed aggregate fines (⩽250 μm), produced by highspeed vertical shaft impact (VSI) crushing of rock types from different quarries in Norway, have been investigated. Among all the methods studied, Xray sedimentation is preferred because it has adequate resolution and requires fewer and more ...
