1. Product Definition & Process<\/h3>\n

Calcined Kaolin 1250 Mesh is a high-end derivative product obtained from natural kaolin through a series of deep-processing steps. The production process primarily includes: raw ore beneficiation and purification, drying, superfine grinding to the target particle size, calcination in specific high-temperature kilns (removing crystalline water and organic impurities, achieving phase transformation), and finally precise classification to ensure a concentrated and stable particle size distribution. The calcination process is key to enhancing the product’s performance, transforming it from hydrophilic to organophilic, making it more suitable for polymer matrix applications.<\/p>\n
