Moreover, their mass fractal dimensions Df, calculated by bi-logarithm relation between setting rates and equivalent circle diameters, were 2.0972.801, and the Df value for granules in the 5th compartment was the highest one among them, indicating that the most compact granules were formed. The least compact granules were observed in the 4th compartment, and the granules in the 1st and 2nd compartments show close compactness. However, the highest average setting rate for granules was detected in the 1st compartment.
