Alumina Rubber Panel

Advantages

1. Wear resistance
High density alumina ceramics have excellent hardness and can significantly reduce wear caused by abrasives such as ore, coal, sand, clinker, cement, and minerals. Compared with traditional steel lining, the service life can be extended several times under the same operating conditions.
2. Excellent impact absorption performance
The elastic rubber layer absorbs the impact energy of falling bulk materials, minimizing the risk of ceramic fracture while protecting the equipment from mechanical impact. This makes alumina rubber panels particularly suitable for handling large particle materials in transfer points, hoppers, and chutes.
3. Reliable adhesive strength
Ceramics and rubber are permanently bonded through high-strength hot vulcanization process to form a durable composite structure. Even under continuous vibration, heavy load, or long-term operation, ceramic tiles can remain firmly attached and will not loosen or fall off.
4. Reduce equipment downtime
Due to its excellent durability, maintenance intervals are greatly extended. Less lining replacement reduces downtime frequency, improves production continuity, and lowers overall maintenance costs in industrial factories.
5. Corrosion resistance and chemical resistance
Alumina ceramics have excellent moisture resistance, acid resistance, alkali resistance, and many industrial chemical properties. This enables the composite lining to maintain stable performance in harsh environments encountered in mining, chemical processing, power generation, and cement production.
6. Flexible installation options
Aluminum oxide rubber sheets can be manufactured using steel backplates, bolts, or CN adhesive layers to accommodate different installation methods, including bolt fixation and adhesive bonding. Customized sizes and ceramic shapes can also be used to match complex equipment.
7. Reduce operating costs
By extending equipment lifespan, reducing wear and tear related failures, and minimizing replacement frequency to the greatest extent possible.

Application

Alumina rubber panels are widely used in industries that experience severe wear and impact simultaneously. The combination of ceramic wear resistance and rubber cushioning helps improve the reliability of equipment while reducing maintenance requirements for various bulk material handling systems.

1. Mining industry
Installed in ore chutes, transfer stations, vibrating feeders, silos, crushers, and conveyor loading points to protect equipment from continuous wear and tear caused by iron ore, copper ore, gold ore, limestone, and other hard minerals.
2. Cement manufacturing
Used for clinker processing systems, raw material hoppers, discharge chutes, bucket elevators, separators, and conveying equipment. Aluminum oxide rubber sheets effectively reduce lining wear caused by highly abrasive cement raw materials and finished products.
3. Coal transportation system
Applied to coal bunkers, conveyor transfer points, crushers, and coal preparation plants, where heavy coal impact and continuous material flow require wear resistance and impact protection.
4. Power plant
Installed in coal-fired power plants to protect coal powder pipelines, coal bunkers, ash removal equipment, and conveying systems, helping to maintain stable factory operation while reducing maintenance downtime.
5. Steel and metallurgical industry
Suitable for sintering plants, blast furnace loading systems, coke processing equipment, and material conveying systems, where abrasive raw materials and high impact loads are common.
6. Port and bulk material loading and unloading
Used for loading hoppers, unloaders, conveyor chutes, and storage facilities, for transporting aggregates, fertilizers, minerals, grains, and other bulk materials, ensuring long-lasting protection of equipment under heavy operating conditions.
7. Chemical and mineral processing plants
Aluminum oxide rubber sheet is an ideal choice for equipment that processes corrosive or abrasive powders and particles, including processing lines for silicon dioxide, phosphate, aluminum oxide, quartz, and various industrial minerals. Its excellent wear resistance and corrosion resistance help extend the service life of equipment while maintaining efficient production.

Technical Data

Production process

To guarantee consistent stable performance of every batch of alumina rubber panel, our factory implements closed-loop quality supervision covering raw material incoming inspection to finished shipment, with dedicated full-time quality inspectors stationed at each production node:

1. Raw Material Strict Screening & Preprocessing

95% alumina ceramic blanks are purchased from self-owned high-purity sintering production lines; each batch undergoes Al₂O₃ content, hardness and wear loss testing before warehousing. Rubber raw materials adopt customized anti-aging flame-retardant formula with automatic precision weighing to eliminate manual proportion deviation. Bottom steel plates receive Sa2.5 sandblasting oxide scale removal to upgrade vulcanization bonding strength.

2. Precision Ceramic Mosaic & Constant-Temperature Vulcanization

Automatic positioning equipment arranges semi-spherical ceramic particles evenly on rubber substrates for uniform gap distribution. Three-layer composite blanks enter flat vulcanizers under 12MPa constant pressure and 145℃ fixed temperature for 25-minute curing, forming integrated chemical bonding without post-assembly glue weak points.

3. Finished Defect Screening & Multi-Item Lab Testing

Workers manually pick out defective liners with ceramic falling, rubber bubbling or steel plate deformation after vulcanization. Qualified products enter independent labs for seven full-item tests including alumina composition, bending strength, wear volume and vulcanization peel force; factory-sealed inspection reports attach to every shipment, supporting third-party designated testing fully.

4. Moisture-Proof Anti-Collision Packaging

Before Delivery Finished liners are separated by shockproof foam sheets, fixed on fumigation-free wooden pallets and wrapped with waterproof plastic film to avoid collision damage during long-distance sea container loading and transportation.
