N2 - The effects of drying air temperature and flow rate, spraying air flow rate and slurry feed rate were investigated on the morphology, size distribution, density and flowability of spray-dried hydroxyapatite granules. Granules having a spherical shape and a smooth surface were prepared at all drying conditions. The granules of uniform size distribution were obtained at high spraying air flow rates and granules of small sizes were collected at high spraying and drying air flow rates, high slurry feed rate and low drying air temperature. The granule tapped density varied from 0.55 to 0.95 g/ml and the bulk density from 0.30 to 0.49 g/ml depending on the process conditions. Granules exhibited relatively poor flow properties due to their small sizes and cohesive surface properties. Thus, by adjusting the spray drying conditions we can control the granule properties.
