The key to the selection and processing technology of ceramic raw materials is to pay attention to

The selection and processing technology of porcelain stone proposed by this project has filled the gap of the selection and processing technology of porcelain stone in China and is at the leading level in the world; the selection and processing technology of kaolin clay has reached the international advanced level.

This achievement is based on extensive research on the processing technology and equipment of the traditional raw material porcelain stone and kaolin most commonly used in daily-use porcelain in China, and has absorbed advanced selected processing technology and equipment at home and abroad. Feasible ceramic raw material selection process technology. It has built China's first ceramic raw material dry and wet selection test line with advanced technology, novel and reliable equipment, flexible combination and strong adaptability.

The technical key of this achievement is: to solve the ultra-fine crushing and classification of ceramic raw materials; to remove harmful impurities such as fine-grained iron and titanium; to increase the content of useful mineral components (Al2O3 content) and fine-grained grade (-2μm) in the raw materials Standardized, serialized raw materials for high-quality daily-use porcelain. After the selection of ceramic raw materials, the content of useful mineral ingredients and -2μm particle size is increased (-2μm content is more than 40%), the impurity content of SiO2, Fe2O3, TiO2 is reduced (Fe2O3 + TiO2≤0.5%), the technical performance of ceramic raw materials With greater improvement, it meets the quality requirements for the preparation of high-quality daily-use porcelain.
