Kaolin Grinding Production Line Share

Kaolin, often called the "industrial MSG," plays an indispensable role in dozens of industries, including ceramics, papermaking, coatings, and rubber. However, naturally mined kaolin must undergo a series of meticulous processes to maximize its value. Grinding, as the core step in kaolin processing, directly determines the product's fineness, whiteness, and performance.

Technological Evolution of Grinding Processes

1. Intelligent Upgrade of Crushing Systems

Modern kaolin grinding production lines have evolved from the traditional two-stage "coarse-fine" crushing process to a multi-stage, intelligent crushing system. The introduction of online particle size analyzers and automatic adjustment devices allows for particle size control with an accuracy of ±5%, significantly reducing energy consumption in subsequent grinding steps.

2. Energy-Efficient Revolution in Drying Processes

Kaolin raw materials typically contain 8-15% free moisture, and traditional drying methods consume over 30% of the total energy consumption of the entire production line. The newly developed "waste heat recovery + microwave-assisted" composite drying technology can achieve energy savings of 40% while also eliminating the particle agglomeration problem associated with traditional drying.

3. The Art of Grinding Equipment Selection

For kaolin products in different application areas, the choice of grinding equipment is becoming highly specialized:

• Raymond mill: Suitable for general filler-grade products with mesh sizes of 400-800

• Vertical mill: The preferred choice for producing high-end coating-grade products with mesh sizes of 1250-3000

• Ball mill: Maintains an irreplaceable position in the ceramics industry
