Zusammenfassung:The invention relates to the technical field of kaolin preparation, and discloses a method for preparing superfine kaolin through multi-force-field regulation and control, which comprises the following steps: adding water into kaolin raw ore to prepare kaolin slurry, and grading the kaolin slurry through a multi-stage hydrocyclone and a horizontal spiral centrifuge in sequence to obtain fine-particle kaolin ore pulp; concentrating the fine-particle kaolin ore pulp by adopting a butterfly centrifuge, and then carrying out superconducting magnetic separation and chemical bleaching; carrying out filter pressing on the bleached kaolin ore pulp by adopting a washing type filter press; and dispersing the filter cake into 55-60% ore pulp by using water and a dispersing agent, feeding the ore pulp into a horizontal grinding and stripping machine for secondary grinding and stripping, and finally dehydrating and drying to obtain the superfine kaolin. The method has the beneficial effects that impurities such as free qu
