Kaolin is a kind of clay and clay rock dominated by kaolinite clay minerals, also known as dolomite. It is widely used because of its good plasticity and fire resistance. Kaolin savings reached 6.72 billion tons in 2020, a year-on-year increase of 61.6%. The value of processing with kaolin gridning mill has increased greatly, and kaolin micro powder mill will open up a new development space.
Development status of kaolin industry
Taiwan, China, South Korea, Vietnam, Japan, Malaysia, Pakistan, Thailand and India are all export destinations. At the same time, China’s annual output of kaolin is 6.5 million tons in 2020 and stable at about 6.4 million tons in 2021. It is mainly used for papermaking, ceramics and refractories, coatings, rubber fillers, enamel glaze and white cement raw materials.
In 2021, China’s kaolin import volume was 142 million US dollars, the import volume was 735000 tons, the export volume was 168 million US dollars, and the export volume was 993000 tons. The high-end kaolin imported for deep processing of kaolin is expensive. In recent years, China’s kaolin micro grinding mill technology has been continuously improved, the kaolin processing industry is mature, and the average import and export price gap of kaolin is less than $30 until 2021.
