Alumina support (inert alumina ceramic ball) is widely used in many fields, such as petroleum, chemical engineering, fertilizer, smelting, medical treatment and environmental protection. Being the covering and supporting material and tower packing for catalyst in the reactor, ceramic ball has the feature of high temperature and pressure resistance, low water absorption, and stable chemical performance. It can not only resist the corrosion from the acid, alkali and other organic solvents, but also the temperature change in production process. The main role of ceramic ball is to increase the distributing spot of gas or liquid, also support and protect the activated catalyst with low strength. Alumina balls are available in following sizes:
1) Nominal sizes: 3, 6, 13, 19, 25, 38, 50
2) Bulk density range (kg/L): 1.6 to 2.5
3) Apparent porosity range (%): 1 to 20
4) Crushing strength range (kg): 50 to 1,600
