In the fields of aerospace, nuclear engineering, and advanced equipment manufacturing, high-performance ceramic materials, due to their high temperature resistance, high strength, and high insulation properties, have become crucial base materials supporting cutting-edge technological development.

Traditional ceramic materials, due to weak inter-particle bonding and poor interfacial compatibility, are prone to cracking and deformation during sintering. The honeycomb grinder is a multifunctional device for continuous production, integrating multiple functions such as powder spheroidization, surface modification, depolymerization, and drying. It can perform a series of process operations such as dry grinding, powder surface modification, spheroidization, and drying. Its unique mechanochemical modification technology can effectively improve the surface properties of the powder. ：

Interface Optimization: Using modifying agents such as silane coupling agents, a nano-scale functional film layer is formed on the surface of the ceramic particles, reducing the surface energy between the particles, inhibiting agglomeration, and significantly improving dispersibility.

Structural Enhancement: By controlling the thickness and composition of the coating layer, the interfacial bonding between the ceramic matrix and the reinforcing phase (such as fibers, whiskers) can be optimized, making the stress distribution more uniform when the material is subjected to load, and improving bending strength and compressive strength 20%-40%.

Functional Expansion: According to the needs, a composite coating layer can be designed to give ceramic materials flame retardant, wear-resistant, and corrosion-resistant properties, meeting the special requirements of aerospace and electronic devices.

For high-temperature resistant ceramics such as silicon nitride and aluminum oxide, the nano-coating modification machine combined with silicon sol-gel impregnation technology can form a gradient densification structure after sintering, effectively inhibiting crack propagation; in nylon, Adding nano-coated ceramic microspheres to engineering plastics such as PP can significantly improve material flowability and dimensional stability, eliminate exposed fiberglass defects, and improve heat distortion temperature and flame retardancy 。
