The analysis of crystal size distribution using the method of population density balance is aggravated by two sources of possible errors: the uncertainty in calculating the population densities (numbers of crystals) from weight amounts of crystals and the necessity of extrapolating the population densities into the range of very small sizes in order to obtain the nuclei population density. Employment of cummulative weight distribution data overcomes both of these difficulties and serves results suitable for design purposes. The comparison of both methods is shown using experimental data on continuous potash alum precipitation.
