Abstract

See full text

The present invention relates to a non-spray-drying, dry-granulation process for making a ceramic particulate mixture comprising from 4 wt % to 9 wt % water, wherein at least 90 wt % of the particles have a particle size of from 80 μm to 600 μm, wherein the process comprises the steps of:

    (a) forming a precursor material;(b) subjecting the precursor material to a compaction step to form a compacted precursor material;(c) subjecting the compacted precursor material to a crushing step to form a crushed precursor material; and(d) subjecting the crushed precursor material to at least two air classification steps, wherein one air classification step removes at least a portion of the particles having a particle size of greater than 600 μm from the crushed precursor material, and wherein the other air classification step removes at least a portion of the particles having a particle size of less than 80 μm from the crushed precursor material.
