Alumina ceramics have excellent mechanical strength, high temperature resistance, wear resistance, corrosion resistance, good insulation performance and durability. Alumina ceramic ring has low dielectric constant, small dielectric loss, high dielectric strength, high volume resistivity, good bending strength, high stability, high compressive strength, and good thermal shock denaturation. It is widely used in thermostats, insulating parts of various small household appliances, various thermal equipment, electric heating equipment, iron structures, shipbuilding, etc. 
Alumina ceramic cylindrical ring Alias: alumina cylinder, cylindrical alumina, high alumina ceramic column, alumina ball column, alumina cylindrical ball, wear-resistant cylinder, alumina column ball, cylindrical alumina ceramic, alumina grinding column , Wear-resistant ceramic cylinders and other
alumina ceramic cylinders have conventional sizes and diameters of ∅15, ∅20, ∅25, ∅30/40/50/60, and the thickness can be adjusted with the diameter. In addition to the normal size, wear-resistant ceramic linings are usually Porcelain caps on the plate such as ∅17.5, ∅22.5∅23.5, etc. can also be used as cylinders. 
Alumina ceramic cylinders are widely used in different types of ceramics, enamel, and glass due to their excellent characteristics such as high lightness, high hardness, high wear resistance, large specific weight, small volume, high temperature resistance, corrosion resistance, and no pollution. The finishing and deep processing of thick and hard materials in chemical, chemical and other factories is very similar to alumina ceramic balls. They are the grinding bodies of fine grinding equipment such as ball mills, pot mills, and vibration mills. The grinding efficiency and durability Wear is also better than ordinary ball stones or natural pebbles. However, the price of alumina cylinders is generally higher than that of alumina ceramic balls. 
Alumina ceramic cylindrical rings are suitable for roller kilns and electric furnaces for producing wall tiles, floor tiles, and household porcelain. It has excellent bending strength at high temperature, and has extremely reliable thermal stability and excellent high temperature impact resistance for products fired within 1400 °C. Alumina ceramics is an indispensable key component of various types of modern high-temperature roller kilns, and it plays the role of bearing transmission products in high-temperature firing.
