This work presents the results of a study concerning on the dry granulation of a porcelain stoneware tile paste. The paste preparation step is very important in ceramic processing science. The ceramic paste was formulated using kaolin, albite and quartz in determined proportions. The raw materials were dry-ground and then microgranulated by using a Eirich granulator of high intensity. The following parameters for the granulated ceramic paste were determined: chemical composition, granule size distribution, morphology, apparent density, tap density, plasticity, Hausner index, and compaction behavior. According with the results the dry process was effective in the granulation process of the porcelain stoneware tile paste.
