Granulation Time in Fluidized Bed Granulators
نویسندگان
چکیده
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.

Fluidized Bed Spray Granulation: Analysis of Heat and Mass Transfers and Dynamic Particle Populations
A model was developed taking into consideration the heat and mass transfer processes in liquidsprayed fluidized beds. Such fluidized beds (FB) are used for granulation, coating and agglomeration. Conclusions are drawn on the relevance of particle dispersion, spraying and drying to temperature and concentrations distributions. In extension, the model was coupled with a population balance model t...
متن کاملA novel approach describing struvite crystal aggregation and granulation in the fluidized bed for phosphorus recovery from swine wastewater
Fluidized bed is commonly used for struvite (MgNH4PO4·6H2O) recovery from wastewater. However, effective methods are lacking to describe the properties of the millimeter-scale struvite pellets in the fluidized bed, with the consequence of not predicting and optimizing the granulation process effectively. In this work, swine wastewater was used as the medium for struvite recovery by using fluidi...

متن کاملInvestigation of Physicochemical Drug Properties to Prepare Fine Globular Granules Composed of Only Drug Substance in Fluidized Bed Rotor Granulation.
The effect of some drug properties (wettability and particle size distribution) on granule properties (mean particle size, particle size distribution, sphericity, and granule strength) were investigated in a high (>97%) drug-loading formulation using fluidized bed rotor granulation. Three drugs: acetaminophen (APAP); ibuprofen (IBU); and ethenzamide (ETZ) were used as model drugs based on their...
متن کاملAdaptive discrepancy based control of continuous fluidized bed spray granulation with internal classification
This paper is concerned with adaptive stabilization of open loop unstable fluidized bed spray granulation with internal product classification by means of nonlinear feedback control. Since the process model is represented by a nonlinear partial integro-differential equation, direct stabilization of the particle size distribution in a Lp or L∞ norm is difficult. To overcome this problem a stabil...
