AB The article presents the results of experimental studies of the process of entrainment of particles of fine fractions from the fluidized bed of polydisperse mixture of granular superphosphate. A review of the main analytical dependencies for determining the amount of entrainment from the fluidized bed is presented. The results of experimental studies of the entrainment process from the fluidized bed of small particles with a size less than 1 mm and large particles with a size more than 1 mm in the interval of gas flow velocities 0.5 - 5.0 m/s are given. The results of calculating the value of fine fraction entrainment from the fluidized bed of superphosphate granules according to the known equations are analysed. The analytical dependence, which is more rational from the practical side, is proposed.
