Abstract A ceramic granule, obtained by granulating at least one ceramic particle into a granule together with a binder, optionally classifying the ceramic granule to remove fine particle having a particle size of not more than 10 mum, moistening the granulated ceramic granule in an agitation fluidized bed under the conditions of not aggregating said ceramic granule and regulating the water content of the moistened ceramic granule by fluidizing and drying the moistened ceramic granule in the agitation fluidized bed in such a manner that the resultant granule has a water content within the range which maintains a flowability sufficient for packing the ceramic granule in a mold in which the ceramic granule exhibits well-balanced properties of a crushing property at a low pressure and an anti-collapse property, excels in flowability, packing property into a mold, and anti-sticking property, and has a well-balanced properties of a crushing property at a low pressure and an anti-collapse property. This ceramic granule can be continuously molded into a ceramic product having a high dimensional accuracy.
