Particle size distribution and structural changes in ...

Jan 10, 2014  Chemical composition and particle size distribution are chief specifications when limestone and dolostone are employed as fillers and fluxes. For instance, the top size of ground limestone for papermaking should be lower than 5 μm and the impurity content should be lower than 1% (Sinton, 2006, Varela et al., 2006, Sampaio and Almeida, 2008).

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.
