The characteristics of grain size distribution of kaolin

The particle size distribution of kaolin is of great significance to the selection and application of ore, and its particle size has a great influence on its plasticity, mud viscosity, ion exchange, molding performance, drying performance and sintering performance. Kaolin ores need to be processed by technology, and whether it is easy to process the fineness required by the process has become one of the criteria for evaluating ore quality. The industrial departments have specific requirements for granularity and fineness of kaolin with different uses. For example, in the United States, the content of kaolin less than 2 m is 90 - 95%, and that of paper filler is less than 2 m, accounting for 78 - 80%.
