Product description
Aluminium oxide ceramic is a kind of ceramic material with alumina (Al2O3) as the main body. Aluminium oxide ceramic has high hardness and density. According to the Al2O3 content, Aluminium oxide ceramics are mainly ZTA ceramics, 99 ceramics, 95 ceramics, 92 ceramics, etc. because of its wear resistance, it is widely used in coal-fired power plants, iron and steel, smelting, machinery, coal, mining, chemical industry, cement, ports and wharfs On all mechanical equipment with large wear, such as pulverizing system, ash discharge system and dust removal system, different types of products can be customized according to different needs.
Product features
High hardness: The Rockwell hardness of alumina oxide ceramics is HRA80-90, which is second only to diamond and far exceeds the wear resistance of wear-resistant steel and stainless steel.
2. Good wear resistance: dry pressing and isostatic pressing molding, high temperature firing, Rockwell hardness HR85-90, wear resistance, impact resistance, convenient construction, etc., which can effectively extend the service life of various equipment and vulnerable parts .
3. Light weight: Its density is 3.6 ~ 3.8g/cm3, which is only half of steel, which can greatly reduce the equipment load.
Aluminium oxide ceramic service life
With the development of the market, the majority of users have higher and higher requirements for the performance, service life, wear resistance and variety of wear-resistant products. They have no longer met the requirements for general wear-resistant parts, and have turned to high value-added, Demand for low-carbon, environmentally friendly, and long-life products.
The service life of the alumina oxide ceramic sheet is related to the size, concentration, speed and scouring angle of the dust particles. The smaller the particle, the lower the concentration, the lower the scouring speed and the smaller the scouring angle, the longer the service life of the alumina wear-resistant ceramic sheet long. Usually in the network tube of the slag powder production line, the specific surface area of the powder is 420～450m2, the concentration is 350g/Nm3, the speed is 28～30m/s, and the scouring angle is 30°. 20mm wear-resistant ceramic sheets can be used for 8～10 year. The raw material mill and clinker mill have better grindability than slag. The same construction thickness has a service life of more than 10 years.

Product process
Paste the alumina ceramic sheet on the adhesive tape to form a 250*250 liner. When installing, paste it directly on the inner wall of the equipment with an adhesive to form a firm anti-wear layer. This process is suitable for pneumatic conveying powder equipment to prevent wear. The advantage is that it is suitable for large-area construction, and the construction is very convenient and flexible. The disadvantage is that it is not resistant to high temperatures. Main application scope: coal mill outlet pipe, coarse powder separator inlet pipe, cone, cyclone tube, fine powder separator powder pipe, elbow, cone, powder discharge machine socket, impeller, primary air duct elbow, Medium-speed coal mill barrel, dust removal pipe and elbow, cyclone dust collector and its pipe
