| Resumen en inglés | In this work the quality of sulphur-coated urea was determined by the urea dissolution rate and analysed by electron microscopy. Particles of urea were coated in a two-dimensional spouted bed, having a 60° slanted base angle and an atomization nozzle installed at the base. Elementary sulphur was liquefied and atomized on the particles. The experiments were planned with the objective of verifying the influences of flowrates of sulphur and atomized air and the temperature of the air used in the spouted bed on the quality of the coated particle surface. The temperature of the spout air and the flowrate of the atomized air showed a significant influence on the quality of the coating |
