摘要: Calcium carbonate is a versatile mineral with diverse industrial applications. Drying necessary processing step in preparation of calcium product. Deep knowledge drying kinetics required order to design an appropriate dryer. The main aim the present study was investigate carbonate, experimentally. Thirteen empirical correlations temperature-dependent constants were used describe thin-layer behavior carbonate. correlation fitting results revealed that all examined acceptable. But, Page best agreement experimental data. effective moisture diffusivity calculated within 8.61 × 10-9 10.40 10-9m2s-1 temperature range 60 90˚C. activation energy also be 6.306 kJmol-1. fitted for can dryer and estimate time various conditions.
