Analysis of the Mean Diameters and Particle-Size Distribution in Powders
The granulometric characterization of a pulverulent material requires quantification of the particle size and its distribution frequency. From these primary data, the mean size (mean diameters) of the pulverulent material is calculated and the data are adjusted to the distribution functions. In this study, the most frequent mean diameters are defined and calculated, and the application of the distribution functions to the experimental results is discussed. It is concluded that the Rosin-Rammler distribution function and a modified Nukiyama-Tanasawa function are the most suitable equations to fit the differential and the cumulative undersize distribution frequencies. This review is accompanied by calculations that illustrate the application of the equations related to this work.
