The problems of experimental and theoretical investigation and analysis of granulometric composition of granules in granulation processes of powdered superphosphates in drum apparatus are considered. The theoretical investigation has been constructed on analytical decision of Fokker-Planck stochastic equation defining evolution of the distribution function of granules on sizes.
