ABSTRACT:
By agglomeration in a high speed mixer spherical granules having a desired granule size distribution are obtained by supplying the agglomeration liquid by means of an atomizer wheel axially positioned in the high speed mixer and by controlling the quantity and evaporation of said liquid in consideration of the changes occurring with respect to water binding ability of the agglomerates during compaction. An apparatus for carrying out the method includes a mixer bowl with an impeller on a central shaft through the bottom of the bowl and an atomizer with an atomizer wheel with its shaft in alignment with the shaft of the impeller.
