The main purpose of this study was to determine the influence of process variables on granulation of ordinary super phosphate. The experiments were performed in a drum with an internal volume of 25 l and the evaluated variables were rotation speed, liquid phase, granulation time and fill level of the drum granulator. Central Composite Design (CCD) was used to choose the experimental conditions. The correlation between data and process variables was established using Multiple Regression. The granulation products were analyzed using standard separators and the Haver CPA photo-optical particle size measurement system. The tendency toward granulation and formation of coarse or fines could be predicted according to the specific surface of the granulation product and the granulation size distribution was found to be greatly dependent on the variable studies.
