Our activated alumina has been developed with high attrition resistance and crush strength, It has larger water adsorption capacity comparing to molecular sieve at high relative humidity and providing long service life with performance at or below dew point specifications. Activated alumina is widely used in large and small dryers. It is appropriate for use in dehydrating gases in both thermally regenerative and pressure swing adsorption (PSA) process.PhysicalparametersItem92%Al2O3Al2O3 (%)≥92SiO2 (%)≤5.35Fe2O3 (%)≤0.2Density (g/cm3)≥3.65Hardness(Mohs)9Compressivestrength(Mpa)2000minFlexualstrength(Mpa)330-350MPaColorwhiteWaterabsorption%≤0.0015WearingLost(‰)≤0.15Features1. High strength, excellent wear resistance, 20 times more than commonly ceramic ball of France or ceramic ball, keep the material high degree of purity.2. High density, high grinding efficiency, shorten 50% grinding times.3. Very good roundness, very smooth and shiny surface, longer using life.AdvantagesComparedwithnaturalstoneballsandnormalceramicballs,aluminagrindingballincreasesby20-40timesinitsperformanceofwearresistance.Itsgrindingefficiencyimprovesby40%-60%andballmillefficiencyaddby30%-40%.Theirtotalcostsonlytake40-60percentofthatofnaturalstoneballs.Inert Alumina Ball are the most widely used support media in the world because of their excellent consistence and reliability. Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.ProductAlumina Ceramic Support Media BallTypeAL-17AL-23AL-99Composition (%)Al2O317-1923-30≥99Al2O3+SiO2≥93≥92≥99.1Fe2O3≤1.0%≤1.0≤0.1MgO≤0.5≤2.5≤0.5CaO≤0.5≤1.5≤0.2Acid Resistance (%)>99.6>99.6>99.8Alkali Resistance (%)>85>85>85Bulk Density (g/cm3)1.35~1.401.35~1.401.80~2.2Specific Gravity (g/cm3)2.30~2.402.30~2.402.30~2.40Free Volume (%)404040Water Absorption (%)<0.5<1.52~6Operation Tem. max (ºC)110011001760Mohs Hardness>6.5>6.5>7.5Crushing Strength (kN/piece)3mm>0.5>0.54>16mm>0.8>0.85>1.213mm>1.5>1.67>319mm>4.15>4.21>525mm>6.07>6.22>838mm>8.52>8.92>850mm>9.7>9.8>15Packaging and ShippingFAQ:Q: What is your experience in your products?A: We have over10 years experience in high alumina ceramics.
