Determination of granule (prill) movement modes in the prilling tower for mineral fertilizer production

The object of research is the mode movement granules mineral fertilizers obtained in towers. subject effect physical and chemical properties granules, their size initial hydrodynamic parameters on speed tower. fertilizer industry characterized by high requirements for production fertilizers, which makes it promising to use granulation plants large unit capacity, tower production. resulting product must have a stable composition, be monodisperse with spherical shape allows long-term storage bulk without auxiliary equipment meet international quality standards. main that used spray type equipment. In such towers, there likelihood crossing pellet flares, getting pellets into walls pelletizing adhesion melt this surface industrial conditions, leads negative consequences. Therefore, determination modes motion still important. Methods mathematical modeling under different conditions were work. Numerical methods solve equations differential equations. As result, an equation was determine components along x y axes. calculation horizontal granule time its working area prilling possible length path direction, diameter torch granules. Provides information preventing ingress magnitude speed, especially vertical component, changes value several times over due change when moving from granulator down This indicates need also take account resistance coefficient time. When deriving equations, simplifications used, solid considered. However, drop begins move (disperser), then crystallizes granule. Comparing results, allowing predict behavior plume ones conclude error 10.5%. work improving describing (speed) will continued.
