Product Description

Rotary kilned calcined Bauxite suppliers 

Product Description

 

  Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .this removes moisture thereby increasing the alumina content. compared to an alumina content of about 57%to 58%in raw bauxite, calcined bauxite has an alumina content of 84%to88%.the heating is carried out in rotary kilns.
Bauxite test indicators:
  High-alumina (containing more than Al2O385%) requires inspection items:
          Al2O3: refractory grade above 85 to 87 percent, 86 percent above the level grinding, welding and above 87%;
          SiO2: refractory grade 6 to 7% or less, grinding stage 5 to 6% or less;
          Fe2O3: refractory grade 1.6 to 2% or less, wear-level of 2% or less;
          TiO2: refractory grade 3.5 to 4% or less,
   Welding grade bauxite and some also require inspection and phosphorus, sulfur, manganese and other projects;
    BD (bulk density): refractory grade 3.10 ~ 3.20g / cm3 or more, ground level, this test does not require welding class;
    L.O.I (loss on ignition): both 0.3%;

Calcined Bauxite Applications:

1. Aluminium metallurgy 

2. Precision casting / Investment casting: 

    bauxite grog fines can be made into mold for precision casting.

3. Refractory: high alumina bauxite’s refractoriness can reach 1780°C.

    It is charactered by good chemical stability and mechanical performance. (Al2O3 ≥48% with low Fe2O3)

4. Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under 2000°C-2200°c in the electric arc furnace.After a series of processing, it can become aluminium silicate refractory 

fiber, which can be made into fiber blanket, plate,cloth.

5. Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall 

lining 

    performance.

6. Producing bauxite cement

7. Abrasives

8. Ceramics industry

9. Chemistry industry for all kinds of aluminium compound.
