1.Introduction of Kaolin
Kaolin is a mixture of inorganic nonmetal,kaolin is calcined to a certain temperature and time in sintering furnace to become calcined kaolin .It is widely used in Ceramics, rubber, plastics, leather, cement, refractory materials, chemical industry and agriculture .
2.Features and advantages
1. High refractoriness
2. Physicochemical stability
3. Volume density high
4. Low porosity
5. Low water absorption
6. Fully calcined
3.Mesh Size :325Mesh, 1250 Mesh ,4000 Mesh ,6000 Mesh ;
