Kaolin Drying and Calcining Equipment
1.Product Introduction
Kaolin Drying and Calcining Equipment is an integrated industrial system designed for the deep processing of kaolin. By removing surface moisture through drying and eliminating structural water and organic impurities via high-temperature calcination, the system significantly enhances the whiteness, porosity, and chemical stability of the kaolin. These systems are widely utilized in high-end manufacturing sectors, including ceramics, papermaking, and coatings.
2.Application
The equipment system typically comprises a Drying Unit and a Calcining Unit, each performing distinct critical tasks:
-
Drying: Reducing the moisture content of wet-processed kaolin slurry from as high as 30%–50% to below 5%. This prevents particle bursting caused by rapid moisture vaporization during subsequent high-temperature treatment.
-
Calcination: Heating the dehydrated kaolin at high temperatures between 900°C and 1100°C. This process transforms the crystal structure from amorphous to metakaolin while burning off carbonaceous and organic impurities, significantly enhancing whiteness and reactivity.
The final product is fine-powdered calcined kaolin, characterized by high specific surface area, strong adsorption, and excellent insulation properties. It serves as an essential raw material for high-end ceramic glazes, paper coating pigments, and eco-friendly adsorbent materials.
3.Working Principle
-
Application: Ideal for large-scale, continuous production lines.
-
Operational Features: The drum is installed at a slight incline. Materials enter from the upper end and are discharged from the lower end during slow rotation, ensuring uniform heat distribution.
-
Configuration: Frequently integrated with pre-dryers (such as rotary drum dryers) to form a streamlined, all-in-one "Drying + Calcining" workflow.
-
Control Precision: Equipped with a PLC-based automated control system to precisely regulate temperature profiles and retention time, guaranteeing consistent and stable product quality.
