vortex granulator

Mathematical calculations for determining the hydrodynamic characteristics of granules movement in the workspace of the vortex granulator, which is the main ultimate process of chemical technology and forms properties of ordinary and porous ammonium nitrate and carbamide, are presented in this paper. Components of a granule velocity and the granulator design impact on them are analytically determined. Comparison of theoretical and experimental studies is performed.

This paper presents the prospective line of studying such chemical process as granulation and the advantages of small universal vortex granulators usage in chemical processes, for example, for the production of nitrogen mineral fertilizers, complex mineral fertilizers and porous ammonium nitrate (PAN). The mathematical calculations for determining the hydrodynamic characteristics of gas flow movement, which ultimately affect the crystallization process in the workspace of the vortex granulator, are described.
