Particle size plays an important role in many industries and applications since it influences many properties of particulate materials. It is a valuable indicator of quality and performance. In mining, there are generally three values to define powders in terms of micron size: Dv10, Dv50, and Dv90.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.Mineral processing - Wikipedia,An important factor in both comminution and sizing operations is the determination of the particle size distribution of the materials being processed, commonly referred to as particle size analysis. Many techniques for analyzing particle size are used, and the techniques include both off-line analyses which require that a sample of the material,
