According to the binder nature, fluidized-bed granulation (FBG) is usually classified as wet or melt granulation. In particular, the industrial urea granulation performed in fluidized beds, is often called “melt granulation” because a highly conc

Mass and population balance equations are used to describe the spray-on melt granulation process in a batch fluidized bed where coating and agglomeration can occur simultaneously. Two different models are considered to describe the agglomeration kine
