What is Granulation

The chapter presents validation of the selection criteria for the construction of the granulation and drying equipment. New forms of the organization of the flows motion in a fluidized bed regime are offered. The steering mechanisms for the motion and the residence time of the disperse phase in a workspace of the apparatus are described. The results of the simulation of the hydrodynamic conditions for the motion of the directional gas flow and the two-phase aerodisperse system are presented. Based on the simulation results, various constructions of the apparatus components are offered. The well-minded construction of the workspace of the apparatus helps to achieve optimized consumption of the heating agent and the minimal residence time of the disperse phase in the apparatus. The computer simulation allowed the authors to offer an algorithm of the optimization calculations of the granulation and drying equipment. New constructive solutions to perform the granulation and the drying processes in the devices with a directional fluidized bed are offered.
