Introduction
The ceramic-rubber composite plate is a new type of wear-resistant composite material that combines the high wear resistance of ceramics with the high elasticity of rubber. It consists of three layers: the top layer is a high-hardness alumina ceramic sheet, the middle layer is an elastic, wear-resistant rubber, and the bottom layer is a steel backing (or a fiber base layer).
This product forms a strong bond between the ceramics, rubber, and steel backing through a high-temperature vulcanization process. It not only overcomes the brittleness and tendency to fragment of pure ceramic liners, but also addresses the poor wear resistance of pure rubber liners. Widely used for protecting industrial equipment under high-impact and severe wear conditions, it is an ideal wear-resistant lining material for industries such as cement, metallurgy, and mining.

Advantage
1.Impact Resistance: It offers excellent cushioning performance and can effectively absorb the impact of ores and other materials falling from a height. While pure ceramic liners offer good wear resistance due to their alumina content, they lack toughness. When the impact force exceeds a certain level, wear-resistant composite liners are required.
2.Easy Installation: It can be easily cut and assembled, making it suitable for installation in various irregularly shaped equipment.
3.Non-Stick & Non-Clogging: The smooth surface of the ceramic layer effectively prevents material buildup and clogging in equipment. In contrast, traditional nylon plates are prone to material adhesion, which reduces work efficiency.
4.The ceramic-rubber composite plate offers excellent wear resistance, impact resistance, and corrosion resistance. Additionally, the rubber elastomer provides excellent vibration damping, which helps reduce noise generated during material conveying.
5.The ceramic-rubber composite plate has a lower density and is lighter than steel plates. Furthermore, due to its high wear resistance, it does not require frequent replacement, saving enterprises significant time and costs.
Application
Applicable as a wear-resistant lining for various types of equipment and pipelines operating within a temperature range of -40℃ to 100℃, such as chutes, hoppers, troughs, loader buckets, coal hoppers, inlet and outlet pipelines of ball mills, coal dropping pipelines, etc.
Connection Methods
Adhesive bonding or bolt fastening: Bond the composite plates to the inner shell of equipment with high-strength organic adhesives, or fasten them with bolts, so as to form a robust and cushioning wear-resistant layer.
