alumina rubber panel
Description
Technical Parameters
Alumina rubber panel - Three in one ceramic lining plate (composed of ceramic, rubber, and steel plate) adopts hot vulcanization process. Alumina rubber panel is made by neatly embedding a certain size of alumina wear-resistant ceramic blocks on the surface of the rubber plate. The surface of the ceramic blocks protrudes with semi-circular ceramic particles, forming a strong grip under belt tension, providing traction for belt operation, and the friction force is greater than that of general wear-resistant rubber plates. The ceramic blocks protruding from the rubber surface create deeper grooves and larger gaps on the surface of the rubber plate than diamond rubber plates.
This customized lining plate can be made of composite materials of various thicknesses and shapes, tailored to specific wear conditions, thus forming a sturdy wear-resistant layer. This product operates within the working temperature range of -50 ℃ to 100 ℃.
The performance of each material in the three in one ceramic lining complements each other, forming an excellent wear-resistant and impact resistant panel, thus exhibiting incredible wear and impact resistance. Under most working conditions, alumina rubber sheets are sufficient to meet the required friction and service life.

Advantages of the Alumina rubber panel
Impact Resistance
Alumina rubber panel exhibit excellent cushioning properties, effectively absorbing impacts from above. For instance, the lining of ore and wear-resistant ceramics, made of aluminum oxide, demonstrates strong wear resistance but lacks toughness. Therefore, it is necessary to opt for wear-resistant ceramic rubber composite plates with a certain level of impact resistance.
Non-stick Material, No Clogging, and Noise Reduction
Compared to steel plates and polymer liners, pure rubber sheets are less prone to sticking and clogging. Moreover, rubber elastomers offer superior shock absorption, thereby reducing noise during material transportation.


Weight Reduction and Easy Construction
Ceramics and rubber have significantly lower densities than manganese steel and high chromium wear-resistant plates, making them lightweight. They can be easily bolted and welded, simplifying operations and facilitating replacement.
Cost Savings
Due to alumina rubber panels' high wear resistance, they do not require frequent replacement, saving businesses considerable time and costs.
Application of the Alumina rubber panel
Mining and steel industries
In the mining and steel industries, alumina ceramic rubber liners are widely used as lining for conveying equipment, mills, and crushers. These lining plates can effectively resist wear, extend equipment life, and reduce maintenance costs.
Chemical industry
In the chemical industry, alumina ceramic rubber liners are commonly used as lining for components such as reaction tanks, pipelines, valves, etc. Its excellent chemical stability enables it to resist the erosion of corrosive media such as strong acids and alkalis
Power industry
Alumina ceramics can withstand high temperature environments, so they are used as linings for high-temperature parts such as boilers and furnaces in the power industry to ensure the stable operation of equipment.
Casting process
During the casting process, alumina ceramic rubber lining plate is used as the inner lining of the mold, providing good wear resistance and heat resistance, improving the quality and output of the castings.
Mechanical and metallurgical industries
In the mechanical and metallurgical industries, alumina ceramic rubber liners are used on various mechanical equipment with high wear and tear, such as coal conveying, feeding systems, powder milling systems, ash discharge, dust removal systems, etc.
Other industries
Raw material feed;Head chute liner;Impact curtains;Chute Liner;Rock boxes;Skirt Boards;Bucket Liner
