Kaolin materials

keyword:Experimental rotary kiln

Description

Kaolin is a soft, white-textured non-metallic mineral, also commonly referred to as "dolomite" in some regions. It derives its name from Gaoling Village in Jingdezhen, Jiangxi Province—renowned as the "porcelain capital" of China, where the mineral was first extensively mined and utilized.

Its mineral composition is predominantly kaolinite, supplemented by halloysite, hydromica, illite, montmorillonite, and minor amounts of quartz and feldspar. Valued for its fine particle size, high whiteness, good plasticity, and chemical stability, kaolin has a remarkably wide range of applications. It is primarily used as a key raw material in papermaking (for coating and filling to enhance paper smoothness), ceramics (as a base material for porcelain and earthenware), and refractory materials. Additionally, it serves as a filler in coatings and rubber, a component in enamel glazes, and a raw material for white cement, among other industrial uses.
