The rotary calciner condition (11500C – 16500C), lining design (monolithic/refractory shapes) and refractory applications vary depending on the product type and kilns. To meet the critical operational conditions and to the at par with the best achieved performance and refectory consumption (1.25kg/t) overseas, specific qualities of Refractories are desired.

The major problems faced with indigenous Refractories used in alumina calciners are high shall temperature and low abrasion resistance. Low cement/Ultra low cement constable (80 – 90% Al2O3) and refractory shapes of tailored properties are essential for overcoming these operational problems and achieving improved performance.
