摘要： A process of producing a kaolin product for paper coating includes mining kaolin ores by hydromechanization and then producing kaolin slurry; classifying by centrifugal sedimentation; chemical bleaching; eliminating iron ions by circular rinsing; removing water by pressure filtration; producing slurry by dispersing filter cakes, in which complex dispersants, pH adjustor and intercalator are added; delaminating; classifying by vibrating sieve; and spray drying: spray driers are restructured by adding insulating layers on packing auger, elevator scoop and bunker at first; the kaolin slurry J which has passed through vibrating sieves is dried in high speed centrifugal spray drying tower and the moisture of kaolin powder is controlled in 3 wt. %-5 wt. %, and the kaolin product for paper coating is obtained. The process characterizes in stable properties, high efficiency, and high viscosity content and fine particle size of the kaolin products produced.
