The effect of operational conditions was studied on the drying kinetics of a slurry droplet in a spray dryer. For this purpose, the mathematical model was developed taking into account the heat and mass transfer resistances inside the droplet. As the result, it was shown that the drying rate of the droplet increases with increasing drying air temperature, air flow rate and slurry concentration, and with decreasing the agglomerate size. It was also confirmed that the heat and mass transfer resistances inside the droplet affect significantly the drying rate.
