Release of Capsulated Mineral Fertilizers Components. Process Simulation

Authors: 

Oleg Nagursky and Yaroslav Gumnitsky

Theoretical investigations concerning the compounds release out of globular capsulated particles within a wide variable range of criteria diffusive complexes have been examined. The effect of capsulated particle size on the process kinetics has been determined. The simplified analytical dependencies have been obtained to calculate the parameters of particles coating for the main soluble nitrogen fertilizer in order to ensure the necessary active time.
