Requirements of ceramic industry for kaolin particle size


Generally, the finer the kaolin is, the better the plasticity and drying strength of the clay is. However, the granularity of the ingredients should be increased for the casting process which requires rapid casting, accelerating the grouting speed and dewatering speed. In addition, the difference of the crystallinity of kaolinite in kaolin will also obviously affect the technological properties of porcelain body. If the crystallinity is good, the plasticity and bonding ability will be low, the drying shrinkage will be small, the sintering temperature will be high, and the impurity content will be reduced. On the contrary, the plasticity will be high, the drying shrinkage will be large, the sintering temperature will be low, and the impurity content will be low. The quantity is also high
