The shell of the vertical mill classifier is lined with a turtle-back mesh.

High-temperature wear-resistant ceramic coating is a specialized protective material designed for extreme environments, particularly those requiring resistance to high temperatures, abrasion, and corrosion. When combined with a turtle mesh framework, this coating significantly enhances the wear resistance and durability of protected surfaces, especially in equipment such as cyclone dust collectors.

**The primary roles of the turtle mesh framework** in the application of high-temperature wear-resistant ceramic coatings are:

1. **Enhanced Structural Strength**: The grid-like structure provided by the turtle mesh offers a strong foundation for the ceramic coating, ensuring it adheres firmly to the substrate surface and is less prone to detachment.
2. **Improved Impact Resistance**: Due to the presence of the turtle mesh, the ceramic coating not only exhibits excellent wear resistance but also enhances resistance to high-speed particle impacts, extending the equipment's service life.
3. **Adaptation to Thermal Expansion**: The turtle mesh framework possesses a degree of flexibility and elasticity, which helps mitigate thermal stress caused by temperature fluctuations, reducing the risk of coating cracking.

**The construction process typically includes the following steps**:

- **Surface Preparation**: First, ensure the surface to be coated is clean, free of oil, rust, and other impurities, and perform necessary grinding to enhance adhesion.
- **Installation of Turtle Mesh**: Cut and secure the turtle mesh to the area to be protected according to actual needs, ensuring it is tightly fitted to the substrate and firmly welded.
- **Application of Ceramic Coating**: Evenly apply or spray the prepared high-temperature wear-resistant ceramic coating onto the surface with the installed turtle mesh, paying attention to uniformity in thickness and coverage.
- **Curing Process**: Carry out the curing process under conditions recommended by the coating supplier (e.g., temperature, time) to ensure the coating fully hardens and bonds tightly with the turtle mesh.

Through the above methods, the combination of high-temperature wear-resistant ceramic coating and turtle mesh framework ensures excellent wear resistance while providing superior high-temperature performance, making it suitable for various harsh working conditions and protective needs.6
