FLUIDIZED BED WET GRANULATION OF UREA USING STARCH BASED BINDER: EXPERIMENTAL AND MODELING STUDIES

Fluidized bed wet granulation is one of the industrial processes used to produce urea granules with a desired size using binder materials. Unlike the commercial binders, the use of biodegradable binders, besides being environmentally-friendly, also potentially offer cheaper processing cost. Howev...
