Technical Parameters
Products Description
92% alumina ceramic tiles are mainly made of alumina powder, which is processed through precision molding and high-temperature sintering. During this process, the ceramic structure becomes dense and stable, allowing the tiles to maintain reliable performance under harsh working conditions. Compared with traditional wear protection methods, alumina ceramic lining focuses on extending equipment usage intervals and maintaining stable production conditions. Proper selection and installation can reduce replacement frequency, improve operational reliability, and provide more predictable maintenance plans for industrial facilities. Different operating environments require different lining designs. Factors such as material particle size, impact force, installation area, and equipment structure can all affect the selection of tile specifications. Therefore, ceramic liners are available in various sizes, thicknesses, and shapes to accommodate flat, curved sections, and specially designed equipment areas.
Advantages
1. Balance performance between hardness and cost-effectiveness
In industrial wear protection, choosing the appropriate ceramic grade does not always require selecting the highest alumina content. Different working conditions require a different balance between performance and investment. 92% alumina ceramic tiles provide reliable wear resistance while maintaining practical cost-effectiveness, making them suitable for many medium to heavy wear environments that require a long service life.
2. Effectively prevent friction between continuous materials
During the transportation and processing of bulk materials, the surface of the equipment is constantly affected by the sliding friction of particles such as coal, minerals, sand, and clinker. Aluminum oxide tiles have a dense structure and high hardness, which reduces surface damage caused by repeated contact and protects the underlying steel equipment from rapid wear.
3. Stable performance under harsh operating conditions
Industrial equipment often operates continuously under constantly changing loads. Ceramic lining maintains its physical properties better than many traditional wear-resistant materials, helping equipment achieve more stable performance over long production cycles. This is particularly valuable in industries where unexpected shutdowns may affect overall productivity.
4. Good chemical resistance
Many processing environments contain acidic, alkaline, or chemically active materials. Alumina ceramics have excellent chemical stability, allowing the lining system to maintain its protective function without being easily affected by common industrial chemicals. This advantage expands the application scope of ceramic protection systems.
5. Reduce equipment maintenance frequency
Wear and tear often leads to frequent maintenance, production interruptions, and increased operating costs. By creating a durable protective layer on the surface of the device, tiles can reduce the frequency of replacement and maintenance work. This helps the company improve equipment availability and achieve better long-term operational efficiency.
Applications
1. Steel industry
92% alumina ceramic tiles are suitable for blast furnace loading systems, sintering plant chutes, hoppers, and dust removal pipelines. They can resist the wear and tear of iron ore, sintered ore, and coke, and can withstand the high temperature environment of steel production systems, thereby reducing frequent shutdowns due to lining replacement.
2. Thermal power industry
Used for powder production systems, coal feeding pipelines, ash discharge chutes, and flue gas pipelines. They protect equipment from wear and tear caused by coal particles and fly ash, and maintain stable performance in the high-temperature and dusty environment of power plants, reducing the maintenance workload of boiler auxiliary systems.
3. Mining and mineral processing
Installed on ore chutes, concentrate pipelines, grading equipment, and ball mill discharge outlets. They can resist the impact and wear of hard ore particles and withstand the corrosion of acidic or alkaline slurries, making them an ideal choice for dry and wet mineral processing production lines.
4. Other general industries
It is also commonly used in coal washing plants, bulk material terminals in ports, chemical material conveying systems, and grain processing equipment. For any equipment with a short service life due to material wear, ceramic lining can provide targeted wear protection solutions.

Quality Control Process
Stable performance begins with controlled production. Each batch of tiles undergoes a fully traceable manufacturing process, with quality checkpoints set up at each critical stage to ensure that the final product meets specification requirements. The production process of 92% alumina ceramic tiles follows the following strict steps:
1. Raw material inspection and formulation
After each batch of alumina raw material powder arrives, it must undergo comprehensive laboratory testing, including crystal size measurement, loss on ignition, moisture content, and impurity content analysis. Only raw materials that meet purity standards can be used for production. The raw material formula is accurately weighed based on the 92% alumina formula, and sintering aids are added in precise proportions to ensure consistent densification during the sintering process.
2. Ball milling and slurry preparation
The mixed raw materials are loaded into a professional ball mill for fine grinding. During the grinding process, operators regularly test the viscosity, flowability, moisture content, and particle size distribution of the slurry. Grinding continues until the particle size reaches the specified fine range, ensuring uniform sintering and fine particle microstructure in the finished product. The unqualified slurry is returned for re grinding instead of entering the next stage.
3. spray granulation
The finished slurry is processed into flowable granular powder through spray drying. At this stage, the inlet temperature, plunger pump pressure, outlet temperature, and slurry temperature are strictly controlled to ensure that the particle size and moisture content of the granular powder are consistent. After granulation, the powder is stored in a dedicated warehouse for aging, ensuring even distribution of moisture and improving the quality of molding.
4. Stamping forming
According to the size and performance requirements of the ceramic tiles, use dry pressing or cold isostatic pressing to shape the granular powder into green ceramic tiles. Strictly control the forming pressure according to the material and thickness specifications, and inspect the size, weight, and surface defects of each batch of green bodies. This step ensures uniform density of the entire tile body and prevents internal defects that may cause cracking during the sintering process.
5. High temperature sintering
The formed green body is loaded into a high-temperature tunnel kiln for sintering. The firing process follows a carefully calibrated temperature curve, with precise control over peak firing temperature, holding time, and kiln car speed. This allows alumina particles to be fully densified through solid-state sintering, forming a robust and dense ceramic structure with excellent mechanical properties.
6. Finished product inspection and sorting
After firing, each tile must undergo a visual inspection and dimensional verification. Workers classify defective products such as deformation, surface spots, dimensional deviations, glaze sticking, cracking, and undercooking. Conduct tests on key performance indicators such as density, hardness, fracture toughness, and wear resistance for each batch of samples to confirm compliance with standards.
7. Packaging and delivery preparation
Qualified products are packaged according to standard export specifications, with cardboard boxes inside and wooden boxes or pallets outside to prevent damage during international transportation. Each package is labeled with clear product information, batch number, and specifications. According to customer requirements, special packaging requirements can be met.
