Abstract
Disclosed herein are granulated kaolin compositions exhibiting at least one of improved material handling properties, low dusting during transit, easy make-down into mineral-water slurries, and requiring less energy to produce than spray dried kaolin products. The granulated kaolin compositions may, in one embodiment, be characterized by a moisture content ranging from about 12% to about 23% by weight relative to the total weight of the composition. In another embodiment, the granulated kaolin compositions may have an average granule size of greater than about 10 mesh. Also disclosed herein are granulated kaolin compositions having a moisture content ranging from about 12% to about 23% by weight relative to the total weight of the composition, wherein the composition is friable when subjected to a shear force. Further disclosed herein is a method for producing granulated kaolin compositions comprising mixing at least one kaolin slurry with at least one predispersed spray dried kaolin and agglomerating the resulting mixture. Still further disclosed herein is a system for producing granulated kaolin compositions comprising a first zone for mixing at least one kaolin slurry with at least one predispersed spray dried kaolin and a second zone for agglomerating the resulting mixture.
