Abstract (en)
1. Process for producing a granulated fine-ceramic mass of high homogeneity and a high degree of fineness from ceramic raw materials, liquids, additives and the like, the component materials being ground down finely and liquid being added and, if appropriate, partially extracted at a later time, characterized in that the component materials are ground down dry or wet, and in that all the component materials or individual component materials are conveyed from above in free fall into and through a vertically arranged vessel, thereby being brought in contact with the liquid or part of it by nozzle spraying, under the effect of turbulence, and being agglomerated.
