Abstract
A method was developed for obtaining a mathematical function for the probability density of particle size when the measured distributions are in terms of size increments. The method is particularly applicable when a measured size distribution does not correspond to the normal, log-normal or Weibull distributions but it can also be applied to these distributions over the limits of the experimental data. An iterative least squares technique is used to fit a partial probability density function over the size range of the experimental data. Particle size data are represented which were initially grouped into seven size increments, but the method is applicable to any number of size increments.Keywords
