Size enlargement of fine powders by wet granulation involves mixing of fine particles with a binder liquid to form larger wet granules and drying them by evaporation of the binder liquid to form larger dry granules. Identification of the time for completion of granulation process is critical as further mixing of dry granules is providing extra energy for their attrition. In a batch fluidized bed granulator, monitoring the bed pressure drop and bed temperature with time can provide information on time for completion of the granulation process. Experimental observations on granulation time and granulation size for wet granulation of urea powder in a lab-scale batch fluidized bed granulator are presented.
