Introduction 

 

Wear resistant alumina ceramic tiles used for mill lining is a high wear-resistant material made mainly of aluminum oxide (AL2O3), supplemented by other ingredients, and sintered at high temperature of 1700 ° C. Wear resistant alumina ceramic tiles used for mill lining have better wear resistance than metal materials and are easy to install. The material handling equipment has been widely used in industries such as steel, thermal power, cement, coal, mining, ports, and chemical industry; Wear resistant conditions such as hoppers, pipelines, elbows, valves, fan blades, chutes, ball mills, feeders, powder separators, ball mills, etc. We can design and produce curved, conical, and irregular products for various aluminum oxide plate linings and lining bricks according to customer needs.

Wear resistant alumina ceramic tiles used for mill lining has high hardness and strong wear resistance. The Mohs hardness reaches level 9, the Rockwell hardness reaches HRA85 or above, and the wear resistance is 271.5 times higher than that of Menggang. It has become a widely used ceramic wear-resistant material in industry.

Although wear resistant alumina ceramic tiles used for mill lining have high hardness, their brittleness is relatively high. If subjected to large impact forces, they can cause breakage. Therefore, ceramic lining plates are not suitable for working conditions with high impact forces. Generally, ceramic rubber composite lining plates need to be used for working conditions with high impact forces, and composite lining plates can cope with larger impact conditions.

Wear resistant alumina ceramic tiles used for mill linings are generally divided into several aluminum contents, including 92%, 95%, 96%, and 99%, with the most commonly used being 92% and 95%. 92% of the liner density is above 3.62g/cm3, and 95% of the liner density is above 3.68g/cm3. The higher the aluminum content, the more stable the performance of the ceramic lining plate and the better its wear resistance.

 

Advantage

 

Wear resistant alumina ceramic tiles used for mill lining have a wide variety of types, high hardness (Rockwell hardness HRA80-90), strong resistance to chemical corrosion, high temperature resistance and toughness, insulation performance and high stability, making them widely used in various industries. This material plays an important role in protecting equipment, reducing maintenance costs, extending equipment lifespan, and improving production efficiency. In addition, Wear resistant alumina ceramic tiles used for mill linings also have advantages in environmental protection and can better meet the requirements of modern production. At the same time, it also has good thermal conductivity, which can effectively diffuse heat and protect equipment from overheating damage. According to the needs of different industries, wear resistant alumina ceramic tiles used for mill linings have various specifications and shapes to choose from. It can be customized according to actual needs to meet the requirements of different devices.
