Summary

The production of granules for the pressing process for the production of tiles is accomplished by spray drying of a ceramic slip. In this process, moisture, particle size distribution, and fluidity of granules are parameters that can be influenced by density and viscosity of slip, pump pressure, and characteristics of the nozzle. In this investigation, these parameters are discussed for two industrial spray dryers. For tow spray dryers it was found that by increasing slip density from 1.560 to 1.620 glcm3, the production of granules increases from 60.0% to 66.7%. Also, with this increase of slip density, the apparent density of granules increased from 0.860 to 0.920 glcm3 which increases the fluidity of granules in the pressing process considerably.
