Abstract

In ceramic tile manufacturing industry, the wet process including wet grinding and spray drying, is widely used for preparing granule. However; dry grinding has been becoming an important process for energy savings and allowing different raw materials usage in tile manufacturing process. In this study, the dry grinding circuit design and operational parameters of high capacity continuous dry-ball mill with separator (BM), vertical roller mill (VRM) and pendulum roller mill (PM) were investigated. As is known, the particle size distribution and the particle shape have effects on the prepared slip features and also the sintering behavior and technological properties of final product. Therefore; the particle size distribution of each grinding systems were investigated for the primary raw materials of feldspar, kaolinite, granite and fired floor tile waste. The particle size distribution of each grinding systems were illustrated in RRSB distribution which allows to compare the size distributions in terms of position parameter dı, that indicates fineness and the parameter n, that indicates the steepness of products either it is narrow or wide distribution. Finally, the analyses of the operating cost of the dry grinding systems were performed.
