​Product Description

Alumina Ceramic Rubber Plate is made of high-quality alumina ceramics and rubber, combining the hardness of ceramics and the toughness of rubber. It has outstanding wear resistance, corrosion resistance, and high temperature resistance, and is suitable for various harsh working conditions. The product has a smooth surface and is easy to install. It is widely used in steel, cement, thermal power, ports, chemical industry, electric power,  and other fields.

​Product Feature

Excellent wear resistance and hardness: The alumina ceramic component gives the alumina ceramic rubber plate excellent wear resistance and high hardness, allowing it to easily cope with harsh working environments with high wear and pressure.

Excellent elasticity and buffering: The addition of the rubber part gives the alumina ceramic rubber plate excellent elasticity and buffering properties, which can effectively absorb shock, reduce vibration, and improve the stability of equipment operation.

High-temperature stability: The high-temperature stability of alumina ceramic allows the rubber ceramic liner to maintain stable performance in high-temperature environments.

Excellent corrosion resistance: Alumina ceramic rubber sheets have good corrosion resistance to most chemicals and can be used in harsh chemical environments for a long time.

Convenient processing and simple installation: It not only retains the hardness of alumina ceramics but also has the processability of rubber, making processing and installation quick and easy.

Good insulation properties: Alumina ceramic rubber sheets also have excellent electrical insulation properties and can be used for insulation protection of equipment.

Application scope
Rubber ceramic lining has a wide range of applications: it is often used in material transmission devices under normal temperature conditions. It is used as a wear-resistant inner layer and can effectively resist the impact of materials. For example, it can be installed inside the silo, the bottom of the hopper, the inside of the mixing machine, the side wall of the coal-dropping hopper, the channel of the coal-dropping pipe, the bottom of the raw coal bunker, the pipes at the inlet and outlet of the coal mill, and the surface of the material chute etc., to extend the service life of this equipment and reduce wear, thereby improving the efficiency and stability of the entire material conveying system.

Application of ceramic rubber composite lining in mines
Mine is responsible for the important tasks of excavation, crushing, and screening of various types of ores, and is one of the typical high-wear industries. The wear and tear problem of mine equipment and its frequent maintenance and replacement have become serious challenges faced by many mines. To deal with this problem, the installation of ceramic rubber composite liners has become a common wear-resistant solution for mine equipment.

Take the cement raw material limestone mine as an example. The limestone needs to be mined from the mountains, and then crushed into 100mm diameter stones in the mine, and then transported to the cement plant through conveyor belts, which will pass through multiple transfer stations. The daily throughput of the transfer station can easily reach thousands of tons, and the transported stones are hard and have sharp edges. To achieve the role of crushing and mixing again, the stones will have a higher height when they fall from the conveyor belt into the hopper of the transfer station. This causes the transfer station hopper and chute to be subject to strong impact and friction.

The hardness of alumina high-hard ceramic exceeds the HRA85 standard. It exhibits excellent wear resistance, while rubber stands out for its excellent impact resistance, vibration and noise reduction effects, and excellent connection and fixation capabilities. The perfect combination of the two forms a ceramic rubber composite lining with excellent performance, which is especially suitable for complex mine working environments. Based on this lining, our company has carefully developed a set of wear-resistant solutions specially designed for mines.

Depending on the location of the drop point of the ore, the drop height, and the different characteristics of the ore composition, the hopper chute of the transfer station can flexibly use different types of ceramic materials. In areas with greater impact force, wear-resistant ceramics with higher hardness and stronger impact resistance, such as ZTA ceramics or 99 alumina ceramics, must be used for fixed installation with a thickened rubber layer and countersunk head bolts. In areas where impact wear is relatively small, more economical ceramic materials can be selected and the thickness of the rubber layer can be appropriately thinned.

The application range of ceramic rubber composite liners is not limited to chutes and hoppers. It can exert an excellent anti-wear effect under normal temperatures, heavy wear, and various working conditions with impact. At the same time, according to the specific needs of different working conditions, suitable ceramic materials can be flexibly selected to achieve optimal cost control while ensuring anti-wear performance.
