FRALCO TabularAlumina Balls
·Tabular alumina ballsare high-density, fully shrunk, coarse crystalline alpha aluminas that havebeen converted to the corundum form.
·Tabular alumina isproduced by sintering ball-formed calcined alumina at a temperature just underthe 3704°F (2040°C) fusion point of aluminium oxide. These tabular aluminaballs are then crushed, graded or screened, and ground to a wide range ofgranular or powdered particle size distributions.
Alumina balls and gravels are well used for liquid aluminium filtration. Different alloyfiltration application is used. The major media type includes: 1XXX, 3XXX,8XXX, alloys filtration media; 2XXX, 7XXX hard alloy filtration media; 5XXX,6XXX, alloy filtration media; high purity filtration media, etc. The flowrate of deep bed filter can range from 2t/h to 90t/h.
Advantages
Good resistance to thermal and mechanical shock
Excellent abrasion resistance
·Appearance
White crystalline granules or powder
Depending on requirements, ball sizes are produced from 1/8 to 1 inch(tolerance ± 1 mm) , aluminum gravels are produced from 3-6mesh to7-14mesh according to different application.
Product Use
Regenerative burner bed applications
Deep bed molten aluminium filtration
