Determination of particle size distribution

In granulometry, 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. … See more The PSD of a material can be important in understanding its physical and chemical properties. It affects the strength and load-bearing properties of rocks and soils. It affects the reactivity of solids participating in chemical … See more PSD is usually defined by the method by which it is determined. The most easily understood method of determination is sieve analysis, where powder is separated on sieves of … See more Before a PSD can be determined, it is vital that a representative sample is obtained. In the case where the material to be analysed is flowing, the sample must be withdrawn from the stream in such a way that the sample has the same proportions of particle sizes as … See more Particle size distribution can greatly affect the efficiency of any collection device. Settling chambers will normally only collect very large particles, those that can be separated using … See more ρp: Actual particle density (g/cm ) ρg: Gas or sample matrix density (g/cm ) r : Least-squares coefficient of determination. The closer this value is to 1.0, the better the data fit to a hyperplane representing the relationship between the response variable … See more Sieve analysis Sieve analysis is often used because of its simplicity, cheapness, and ease of interpretation.
