Product Description Alumina Ceramic Ball Alumina Ceramic Ball shows an excellent capacity instrength, chemical stability and thermal stability. It alsohas a good resistance to high temperature, high pressure,acid, alkali and various organic solutions. The alumina ballhas been most often used as catalyst support in petroleum,chemical fiber plant, aromatic factory, catalytic reforming unit , fertilizers, natural-gas,environmental protection and more.ProductHigh Alumina Ceramic BallTypeBS-71-90BS-91Composition (%)Al2O371-90≥99Al2O3+SiO2≥90≥99Fe2O3≤1.0%≤1.0%MgO≤2.5≤5CaO≤1.5≤2.5Acid Resistance (%)>99.6>99.8Alkali Resistance (%)>85>85Bulk Density (g/cm3)1.35~1.401.80~2.2Specific Gravity (g/cm3)2.30~2.402.30~2.40Free Volume (%)4040Water Absorption (%)<8<8Operation Tem. max (oC)14001760Mohs Hardness>6.5>7.5Crushing Strength (kg/piece)3mm35406mm708013mm40058019mm75090025mm1000120038mm1600180050mm180021501.High wear-resistanceThe alumina balls' wear-resistance is higher than the common alumina balls'. When it is working, the ball won't pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze. 2.High bulk densityThe high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it canimprove the grinding efficiency. 3.High thermal resistanceCan withstand temperatures above 1400 degrees
