High temperature calcined bauxite homogenized material is made of mixed bauxite different grades, ground to a fine powder of about 800 mesh by a vertical ball mill, and then use low temperature superconducting magnetic separator to remove iron. It is produced after chemical pulping, mixing, spray granulation, compression molding, drying and dewatering, and calcination at a high temperature above 1600 degrees.
The calcined bauxite homogenized material adopts a unique iron removal process in the whole industry to ensure that the iron content meets standard before homogenization. The required target value is maintained long-lasting and stable. The product has high density (above 3.4g/cm3), low water absorption (within 0.8%), low porosity (within 1.5%), low iron and stable and controllable (1.5%) Within), aluminum content is high and can be customized adjustment (83%-90% order adjustment), corundum phase can reach about 15%, uniform and compact structure, blue color, stable firing and no underfired materials, which can meet the requirements of different users different requirements.
