Alumina ball have the advantages of high strength, highstabilities to chemical and thermal circumstances. It can beresistant to acid, alkali, salt and all organic solvents. Beingused as a support and a covering material in reactors in oilrefinery, chemical, fertilizer, natural gas and environmentalprotection industries, it can improve the distribution of gas &liquid and protect the catalyst from shocking by the rushingfluids.

The activated alumina balls as deep drying used as the dryer forsome industries such as oxygen industry, textile industry, gasdrying in electronics industry, air drying in automationinstruments, as well as dryer and decontaminating agent forfertilizer, petrochemical and other industries (dew point can be upto -40 degrees), in air separation, the dew-point adsorption ofpressure change can up to -55 degrees. It is a high effective dryerfor dry deeply in micro-water. It is an ideal dryer for non-thermalregeneration device.

The product with the advantage of:
1. The dry depth can below the dew point temperature -70degrees
2. High watrer absorption
3. Static adsorption capacity: 18± 1
4. Large specific surface area
5. Higher crushing strength
6. Strong mechanical strength
7. Wide size: 3-5mm, 4-6mm, 5-7mm, 6-8mm, 8-10mm, 10-12mm.
