Studies on effect of process parameters on particle growth in a fluidized bed granulator

Abstract

In present work effect of various process parameters affecting the particle growth in a FBG is observed by performing experiments. The effect of the process parameters such as amount of liquid to be sprayed (V), fluidizing gas temperature (T), fluidizing gas flow rate(F) and amount of bed materials (W) on the growth rate of particles fluidized in a fluidized bed granulator is studied accordingly. The correlation for particle growth is also derived using dimensional analysis method. The dimensional analysis method adopted in this work is exponential in nature unlike the conventional method. The experimental value of particle growth and the calculated values of the particle growth obtained through dimensional analysis are compared. The results found from the comparison shows good agreement with each other. The optimization of the process parameter has been carried out to improve the performance of the fluidized bed granulator. MATLAB coding is developed for the optimization of developed correlation for particle growth using Interval halving method.
