Abstract
Abstract The calculation method based on generalisation of the experimental data and results of mathematical modelling is proposed for prediction of the size of granules and efficiency of their production depending upon the centrifugal granulation process parameters.
Keywords: boron-containing granules, deposited layer, centrifugal spraying, heat content of detaching droplet, prediction, process productivity, particle size distribution, distribution density
