11.25 Clay Processing - US EPA

2015-9-10  In the dry process, the raw material is crushed to the desired size, dried in rotary dryers,pulverized and air-floated to remove most of the coarse grit. Wet processing of kaolin begins withblunging to produce a slurry, which then is fractionated into coarse and fine fractions usingcentrifuges, hydrocyclones, or hydroseparators. At this step in the process, various chemical methods,such as bleaching, and physical and magnetic methods, may be used to refine the material. Chemicalprocessing includes leaching with sulfuric acid, followed by the addition of a strong reducing agentsuch as hydrosulfite. Before drying, the slurry is filtered and dewatered by means of a filter press,centrifuge, rotary vacuum filter, or tube filter. The filtered dewatered slurry material may be shippedor further processed by drying in apron, rotary, or spray dryers. Following the drying step, the kaolinmay be calcined for use as filler or refractory material. Multiple hearth furnaces are most often usedto calcine kaolin.
